Bill Brennan, CEO
Thank you, Dan. Good afternoon and thank you to everybody for joining the call. During this call, I'll review Credo's fiscal Q2 results and share why we remain excited about our future prospects. After I conclude, Dan Fleming, our Chief Financial Officer, will provide a detailed review of our financial results and expectations moving forward. Credo is a pure play high-speed connectivity company. We built our first solutions for the ethernet market and are extending into other standards-based markets as the need for higher-speed connectivity increases exponentially. Today, our product families include integrated circuits or ICs, active electrical cables or AECs and service chiplets. Our intellectual property or IP solutions consist primarily as SerDes licensing. Our connectivity solutions address both electrical and optical applications at port speeds currently ranging from 50 gigabits per second up to 1.6 terabits per second. All our product and IP solutions leverage our unique application-specific SerDes portfolio, enabling us to deliver optimized, secure and high-speed solutions with better power efficiency and cost. This has led to high growth rates with hyperscale customers and the ecosystem of suppliers that provide the infrastructure to these data centers. Credo continues to be one of the fastest growing companies in the semiconductor industry, and I'm pleased to report that we achieved record revenue of $51.4 million in the October quarter, an increase of 94% year-over-year and 11% sequentially. I'll now give a brief update on our progress across our various solutions, starting with AECs. For AECs, we continued to deliver strong execution as the pioneer of this product category. In-rack, low-speed cable connections have historically been made with passive copper DACs. As single lane speeds increased to 100 gigabits per second, DACs became obsolete due to signal integrity and physical size constraints. The industry assumption has been that when DACs are dead, optical cables or AOCs would take their place. Credo saw an opportunity to develop a broad product family of AECs that deliver half the power, half the cost, and with 10 times better reliability than AOCs. We also saw the opportunity to offer compelling functionality that enables our customers to innovate on server rack and switch rack architectures. Industry analysts are now forecasting AECs to grow to a multi-billion dollar market in the next four to five years. We continue to ramp volumes with our first customer as they broaden deployments of the new dual-tour architecture enabled by the Credo AEC. We expect the ramp to continue in the calendar 2023 and we're developing multiple AEC solutions to solve for their future roadmap of higher-speed deployments. I'm happy to report that Credo has completed the stringent qualification with our second hyperscale customer. We expect to begin our revenue ramp near the end of this fiscal year and expect meaningful contribution in fiscal 2024. In addition, we are engaged in developing advanced AEC solutions with this customer for their next-generation server rack and switch rack applications, as they move to 100 gig single lane speeds. We have also further broadened our traction in the market. We're currently in qualification with a third hyperscale customer for a 400 gig port switch rack application, and yet with another hyperscale customer, we're engaged in developing AECs for two future architectural deployments. Although hyperscalers are clearly our primary focus, we've sold our AECs to dozens of customers, including data centers, 5G carriers, networking OEMs and ODMs, as well as others in the ethernet ecosystem. Finally, Credo is very proud to have introduced the industry's first 1.6 terabit per second connectivity solution at OCP, which will be a critical enabler for the 51 terabit per second switch generation. This reinforces Credo as the leader in the AEC market. Now moving to our optical solutions category, as we do across all our product solutions, Credo focuses on delivering disruptive solutions that are optimized for speed, reach, power, and cost. Our optical solutions include DSPs, laser drivers, and TIAs found in both optical modules and AOCs, and span the breadth of applications with 50 gigabits and 100 gigabits per second single-lane speeds, including 50 gig, 64 gig, 100 gig, 200 gig, and 400 gig modules. In the October quarter, we announced several new 100 gig per lane products, including our 800 and 400 optical DSPs with integrated drivers and they've been met with great customer enthusiasm. In addition to engaging the optimal module customer base directly, our go-to-market strategy has grown to include the joint development model or JDM that is focusing on the end customers of our optical module manufacturing partners. These include data center, 5G, PON, and fiber channel end customers as a means to have the end customer pull Credo’s through to design wins by specifying our solution. To date, we've been successful with JDM engagements with two hyperscalers and a Tier 1 OEM. We are now actively engaging all data center customers directly and teaming with optical module partners to jointly pursue our end customers. I'm pleased with our progress as we now have line of sight on new engagements with several data center and 5G customers across a wide range of applications including 200 gig, 400 gig, 800 gig, and 50 gig solutions. I'll note that we see the process from initial win to qualification to volume ramp as taking longer in the current environment than we had anticipated a year ago. With that, our rental material revenue shifted somewhat, but our opportunity remains the same. We continue to play the role of the structure in the optical market and we will gain share over time given the distinct efficiencies we deliver in the combination of performance, power, and cost. Based on our increasing customer traction, we look forward to announcing meaningful customer wins and growth in our optical business. Regarding our Line Card PHY solutions, Credo has established leadership for ethernet Line Card PHY solutions at 50 gig and 100 gig per lane speeds. This includes MACsec PHYs for high security applications needing encryption, as well as retimer and gearbox solutions. Our customers again include leading hyperscalers and networking OEMs and ODMs. As single lane speeds increased to 100 gig, the demand for Line Card PHYs increases due to the signaling integrity challenges that come with higher speed copper connections. We also see a trend toward greater demand for encryption driving increased demand for MACsec PHYs. A highlight from the OCP show in October was Meta showing the use of our Osprey 800 MACsec PHY in one of their critical deployments. Also in October, we announced our Screaming Eagle 100 gig per lane solution, a long-reach DSP retimer device with 1.6 terabits per second of bandwidth. This product has received great market reception, due to its combination of performance and power efficiency. We have sampled it to many leading OEMs and ODMs and are already kicking off design engagements. Based on our current market position, product positioning, and customer engagements, we expect solid growth and continued share gain in the market. And finally, I'd like to give an update on our SerDes IP licensing and SerDes Chiplet business. We've received very positive feedback from customers on our five-nanometer and four-nanometer 112 gig IP SerDes announcement and it confirms that Credo's solution offers a 40% to 50% power advantage over our competition depending on the reach required in the application. This highlights that Credo has extended what we refer to as our N minus one process advantage, which means to compete with the power efficiency of Credo’s five-nanometer and four-nanometer solutions, our competitors will need to move to three-nanometer. As every industry seeks to lower its carbon footprint, Credo’s Core SerDes technology is delivering on the need to lower electricity use. We're also an early leader in the chiplet market and are in production with multiple customers. Notably, Tesla selected Credo certified the N chiplets for their Dojo supercomputer program. Going forward, we're excited about the prospects for chiplets in light of the UCIE consortium. This Intel-led consortium, where we're a contributing member, is coalescing to standardize the broad use of chiplets inside servers. In summary, we remain highly encouraged about Credo’s prospects due to our current solutions and production near and mid-term opportunities we're deeply engaged in, and longer-term opportunities in emerging markets. Today, we remain focused on delivering strong accretion in our fiscal 2023 and we continue to expect to achieve at least $200 million in revenue, representing more than 88% growth, compared to fiscal 2022. I'll now turn the call over to our CFO, Dan Fleming, to provide more details on our second quarter and give guidance on Q3.
Dan Fleming, CFO
Thank you, Bill, and good afternoon. I will first review our Q2 fiscal 2023 results and then discuss our outlook for Q3 of fiscal 2023. As a reminder, the following financials will be discussed on a non-GAAP basis unless otherwise noted. I'm pleased to share with you that in Q2, we achieved another quarter of record revenue at $51.4 million, up 11% sequentially and up 94% year-over-year. Sequential growth was driven by strong revenue growth of our products, which also reached a record of $48.1 million for the quarter, up 33% sequentially and up 143% year-over-year. This growth in product revenue was led by a continued wave of AEC adoption. The fundamental driver of our product growth, a strong HSBC expansion outlook at the highest speeds, remains in place in the face of an uncertain economic and geopolitical landscape. Our IP business generated $3.3 million of revenue in Q2. IP remains a strategic part of our business, but as a reminder, our IP results may vary from quarter to quarter, driven largely by specific deliverables to pre-existing contracts. While the mix of IP and product revenue will vary in any given quarter over time, our revenue mix in Q2 was 6% IP, well below our long-term expectation for IP, which is 10% to 15% of revenue, as the timing of IP deliverables and therefore IP revenue recognition shifted during the quarter. We continue to expect IP as a percentage of revenue to come in above our long-term expectations for the fiscal year. Due to the revenue mix between product and IP this quarter, our gross margin came in at 54.9%, below our guidance range. However, more importantly, our product gross margin was 52.6% in the quarter, up 80 basis points sequentially and up 4.8 percentage points year-over-year. This product margin expansion is principally due to leverage from our strong product growth. Total operating expenses in the second quarter were $25 million, within our guidance range and up 37% year-over-year, as we scaled the organization for growth. I think it's important to note that this is considerably below our 94% year-over-year revenue growth. We generally expect that our top line will grow at least twice as fast as our OpEx for the foreseeable future. With this, we expect to continue to deliver considerable leverage in the business. Our OpEx increase was driven by a 38% year-over-year increase in R&D as we continue to invest in the resources to deliver innovative solutions. Our SG&A was up 34% year-over-year, as we continue to build out public company infrastructure. We delivered operating income of $3.4 million in Q2, an improvement of $5.6 million year-over-year but down 41% sequentially. Our operating margin was 6.6% in the quarter, an improvement of 15.1 percentage points year-over-year but down 561 basis points sequentially due to revenue mix that resulted in lower gross profit. We delivered net income of $2.4 million in Q2, an increase of $5.7 million year-over-year and down 55% sequentially. Cash flow from operations in the second quarter was $1.8 million, an increase of $27.7 million year-over-year and an increase of $14 million sequentially. CapEx was $5.7 million in the quarter, driven by production mask spending. And free cash flow was negative $3.9 million, an increase of $25.7 million year-over-year and an increase of $13.6 million sequentially. We ended the quarter with cash and equivalents of $240.5 million, a decrease of $3.2 million from the first quarter. This decrease in cash was a result of continued working capital investments to support our top-line revenue growth. Our accounts receivable balance decreased to 5.5% sequentially to $51.8 million, while days sales outstanding decreased to 92 days, down from 107 days in Q1. Our Q2 ending inventory was $47.8 million, up $10.8 million sequentially as we continue our product ramp. Now turning to our guidance for the third quarter, we currently expect revenue in Q3 fiscal 2023 to be between $54 million and $56 million, up 7% sequentially at the midpoint and 73% year-over-year. We expect Q3 gross margin to be within a range of 59% to 61%. We expect Q3 operating expenses to be between $25 million and $27 million. And finally, we expect Q3 weighted average diluted share count to be approximately 160 shares. And with that, I will open it up for questions.
Operator, Operator
Thank you. Our first question comes from the line of Quinn Bolton with Needham & Company.
Quinn Bolton, Analyst
Congratulations on the strong product results. Bill, I wanted to start with the AEC business. It seems you are continuing to expand your hyperscale relationships, but could you discuss the growth? I believe you mentioned that some of these customers are looking at switch applications instead of server applications. Could you elaborate on that? Are you referring to the distributed to segregated switch chassis applications for the third and fourth hyperscaler, as well as the switch application for your second hyperscaler?
Bill Brennan, CEO
Yes. Let me say that we really have two opportunities for AECs within the switching hierarchy and the server racks as well. So the largest opportunity that we see are server racks and the market forecasters show that, that market in comparison to the disaggregated chassis or what we call switch racks market, it's probably a five to one. Now in the switching architecture, it's really a big choice between sticking with what has traditionally been most popular, which is a big chassis filled with switches connected internally over a backplane. To the segregation, which means pulling those switches out of the chassis and basically stacking them vertically in a rack, those backplane connections become connections between the switches within the rack, 2.5 meters or less. And so we fully expect that over time each data center customer is going to make their own decision about the architecture that they pursue, but we're encouraged with the fact that as switching lane speeds increase to 50 gig and 100 gig that for those customers that are moving or have been using switch racks, compared to chassis that our solution is naturally getting picked up.
Quinn Bolton, Analyst
Understood. Second question just on the competitive landscape for the NIC to TOR application, I know the first couple of hyperscale you're working with, I believe you're using proprietary or non-standard cables? Are you seeing any evidence that those customers are looking to second source those designs? Or do you feel pretty comfortable that Credo remains the sole source of those cables for the foreseeable future, which hopefully would extend that at least a few quarters?
Bill Brennan, CEO
So I think that there's still question that the data center customers generally speaking want multiple sources. So that's absolutely part of the world that we live in. My feeling is that more and more as the data center customers recognize that they can add functionality to an AEC that they haven't even been able to think about with racks or optical solutions. The idea of having this fabric become more intelligent, it's natural that the team that we've built, which is a large team of engineers and different functions to be able to entertain specific requests for added functionality to the AEC. So we're open for business. If the engineers within the data centers that we're working with have ideas, we'll entertain those ideas as a way to make their jobs easier, make the innovations better from their end from a server rack or switch rack perspective. Now competitively, we've talked about the competitive moat that we've established and the fact that I've got the team that's doing the full system integration. It's not as if selling a chip to a copper cable manufacturer really opens that door for this kind of innovation. So I think that, yes, we naturally see competitors, we naturally see our customers wanting to second source. And I think that we still haven't seen competitors in the wild in the labs of our customers. We've heard about competitors' attention to enter the market. We've seen static demos where they'll have a cable that's not hooked up to anything and they will describe what the cable does. And we've seen demos with evaluation boards that are connected to passive copper cables. So these are far from actual qualification at a hyperscaler. And I think that when we look at the OCP Conference in October, it was a really great measure of our leadership, especially in contrast to the other competitors. I think that anybody that attended the conference could not avoid seeing purple, which is the color of our cables. We were the purple AECs were ubiquitous from end-to-end on the show floor. And to note the progress that we've made year-over-year, last year we showed the world's largest router to date, a three rack deployment that made up of 350 terabits per second router. This is built with 400 gig ports, each with eight lanes of 56 gig or 50 gig. This year, we showed the clear benefit of going faster from the lane speed and wider with the number of lanes. And so we introduced our 1.6 terabits per second AEC at this show, 16 lanes of 100 gig and we demonstrated that same capacity or that same bandwidth, the 350 terabits per second in a single rack deployment. And so this was one of many, many demonstrations that we gave and it was just clear to anyone who saw that just physically if you can see it, we're far ahead of our competition.
Quinn Bolton, Analyst
Great. Thank you for all that color, Bill.
Operator, Operator
Thank you. And our next question comes from the line of Toshiya Hari with Goldman Sachs.
Toshiya Hari, Analyst
Good afternoon. Thanks so much for taking my questions. First one for you Bill, based on the fact that you're reiterating the full-year guide, you guys are clearly doing really well. But curious if you've sensed any change in customer behavior, whether it’d be the large hyperscalers or some of the enterprise OEMs across your business? Have you seen any projects get pushed out or downsized? Or is the adoption of AEC for instance too strategic and too important for your customers to really tweak projects even going into fiscal year 2024? Thanks.
Bill Brennan, CEO
Yes, I think that what we see in our customer base is really two different threads. We have seen a reduction in CapEx and a delay within our Chinese hyperscale customers. There's no question about that over the past quarter. We've seen kind of a shift in the ramp to high volume on the next generation optical. And that's I think everybody is well aware of the macro situation in China. And these hyperscalers don't necessarily serve a wide customer base globally. And so the second part is really the U.S. hyperscalers, and although we've heard that there may be a slight bending of the curve. We haven't heard that anyone is going to decrease spending year-over-year. And these are with the customers that we're engaged with that we've ramped production and we will ramp production with, so it might be a slowing of the growth, but the growth still is very significant. I will reiterate that for us, it looks a little bit different, because we haven't reached the point of saturation and so every new product ramp that we see is next generation better than the current generation technology. And so if anything, there's still a fierce competition amongst data centers to deliver better services to their customer base in order to win market share. And so we see that there is a very, very consistent pull for next generation better than technology to get better productivity, to get better performance. And even in an environment like this at a macro level, that becomes critical to be able to differentiate. So we still remain quite bullish on the customers that we're ramping. We haven't seen any major shifts.
Toshiya Hari, Analyst
That's great. Thank you. And then as my follow-up, on the second customer in your AEC business, you talked about revenue recognition toward the end of this fiscal year and then a meaningful ramp in fiscal 2024. I understand you can't give too specific with these customers, but I was hoping you could compare and contrast the ramp that you're expecting in fiscal year 2024 with the second customer vis-a-vis what you've experienced so far with the first customer. I think you've talked about a potential uplift in pricing just given the complexity. But if you can kind of level set us on your thoughts there into fiscal year 2024, that would be super helpful. Thank you.
Bill Brennan, CEO
We have been quite satisfied with our progress with the second customer since we engaged with them over a year ago. We provided samples of the unique cable we developed in December last year, and we have now completed a rigorous qualification process. We are ready to ramp up production as soon as they are prepared. Their schedule has been consistent over recent quarters. In contrast, our first customer was transitioning to a new architecture without necessarily changing their servers. They maintained a high volume of deployments while attempting to improve floor space and equipment usage. This led to some delays in their plans. The significant difference with the second customer is that they are introducing a completely new generation of technology, which has created a strong demand for timely deployment. We are very encouraged by this development.
Operator, Operator
And our next question comes from the line of Vivek Arya with Bank of America.
Vivek Arya, Analyst
Thanks for taking my question. I actually had two for the first one, Bill you mentioned the engagements for the third and fourth hyperscaler also that seems like a positive. I'm curious, the adoption of AEC seems like a no brainer on surface? What is the main pushback that you get? Is it just a matter of time? Is it the ramp of a certain speed? Is it 400 gig or 800 gig? What do you think drives that sharp inflection upwards with multiple customers?
Bill Brennan, CEO
I believe there are two main factors that make people consider the AEC solution. The first factor is the added functionality, which sets us apart and is evident in our first customer's success with 25 significant lanes. If you required something special, you could manage with DACs. The second customer demonstrates a blend of functionality and speed. As more clients transition to 50 gig lanes, they want to avoid the signal integrity and form factor issues associated with DACs. Hence, speed is another significant factor. We view the 50 gig per lane market as a transitional phase; some will face deployment challenges while others will find it almost a default choice. They recognize that AECs consume half the power and cost, while being much more reliable and durable than AOCs. For shorter in-rack connections, decision-making is straightforward; without the issues posed by DACs, customers will opt for AECs, and we’ve observed this universally. As we move toward 100 gig, it becomes merely a matter of time. There will certainly be no DACs then, making the choice a comparison between AECs. We believe we've settled that debate, as people will choose AECs due to the significant capital and operational expense benefits. Examining the total cost of ownership, AECs clearly present a better option, especially considering that installers won’t damage cables while installing a large number in tight spaces. Thus, the design is much more robust.
Vivek Arya, Analyst
Got it. And for my follow-up, maybe once you've done in your Q2, it seems like IP sales were $5 million to $7 million, kind of below expectations, but you're more than made up for it, because of the upside on the product side. I'm curious what is the expectation for this IP in Q3? And do you expect to make up for that $5 million to $7 million shortfalls that you had in Q2, because I think you mentioned something about a shift. So is the Q3 just that the missing part of the IP revenue from Q2 that comes into Q3? Or just how should we look at Q3 and what happened to that missing IP revenue from Q2? Thank you.
Bill Brennan, CEO
Yes, thanks. So the important thing to note here is that there is no change in our expectation for IP revenue for the full year. So in other words, our revenue mix for fiscal year 2023 is exactly what we have expected it to be for the year plus that we've been talking. And also bear in mind that for the full-year, we expect IP revenue to be above our long-term target, which is 10% to 15% of the overall revenue mix. But we've talked a lot about historically about the quarter-to-quarter variability in revenue when it comes to IP. And this is largely driven by ASC 606 and the way the revenue recognition rules work around license revenue where we recognize the lion's share of the contract value on most of our contracts at the point of delivery of that IP database. So the last two quarters, Q4 of fiscal 2022 and Q1 of fiscal 2023 we happened to be on the higher end of revenue contribution from IP, but that of course swings both ways. One of the things that we track critically from a gross margin perspective of course is our product gross margin and that has continued to expand as we've increased our product shipment volumes. In fact, it was up 80 basis points the product gross margin. So we're quite pleased with our margins for the quarter and we're exactly where we expect to be for the full-year. Hopefully, that helps.
Operator, Operator
And our next question comes from the line of Richard Shannon with Craig-Hallum.
Richard Shannon, Analyst
Hi, guys. Thanks for taking my questions. Dan, I guess, I want to follow-up on the topic of product gross margins. If I'm running my numbers right here and if I exclude the product NRE from the calculation, it looks like our product margins were actually down very slightly. Am I calculating this right? And if so, can you help us understand the dynamics that took that down slightly?
Dan Fleming, CFO
Yes. I wouldn't read too much into that. We look at product gross margin a little bit more holistically. And if you look at the elements that come into the other cost of goods sold bucket, that similar to our IP revenue can vary quite a bit quarter-over-quarter. So the way our view is that from an overall product gross margin perspective as our volume continues to increase at this stage, where we are as a company, we should have that a slight uptick in our product gross margin. But you're right, that excluding NRE in this particular quarter, it did tick down a little bit if you just look at the product margin.
Richard Shannon, Analyst
Okay. And then as we go forward especially if I think most people are assuming that your AEC mix is going to increase here, we should expect those product gross margins excluding NRE again to grow if very slightly, is that fair?
Dan Fleming, CFO
Yes, that sounds accurate. Our long-term model remains unchanged, with 10% to 15% of our overall revenue expected to come from IP and the rest from product sales. We aim for a gross margin of 63% to 65% in this long-term framework, which we define as over three years. We have mentioned previously that we anticipate an expansion in gross margins this fiscal year primarily driven by increased scale. Additionally, there are factors expected in fiscal years 2024 and 2025 that will enhance product margins. A significant development is that AEC has been growing faster than we expected, which will have a positive margin effect as we look toward fiscal year 2024. On the other hand, the ramp-up for optical has been slower than anticipated, which may slightly affect fiscal year 2024 as well. Overall, we project that our corporate gross margin for fiscal year 2024 will be comparable to the total for fiscal year 2023.
Richard Shannon, Analyst
Okay, perfect. Thanks for that detail, Dan. Bill, maybe a big picture question for you. Obviously, Ethernet is your dominant protocol standard you're supporting and obviously a lot of growth opportunities there. But you've talked about USB and PCI Express in the past and I think you've even alluded here recently to cable opportunities, AEC opportunities that exist with one or both of those. Maybe you can just kind of give us a big picture on your thought process on when those technologies and products start contributing more meaningfully to your outlook?
Bill Brennan, CEO
For PCIe, we plan to enter the market significantly when it transitions to Gen 6. We will also develop a product that is compatible with earlier generations, expecting to gain traction before Gen 6. We believe our major market entry will be around 2025 or 2026, depending on schedules and server developments. We see a substantial market opportunity for PCIe, which can be evaluated through PCIe retimers in servers and UCI equipment. Regarding USB, we anticipate a similar timeframe for opportunities, particularly with the 80 gigabits per second or two lanes of 40 gig PAM3. In terms of AEC opportunities, we recognize potential in both segments and see it as a natural extension similar to how we approach AECs for Ethernet. However, in the consumer market for USB, it seems likely that the companies manufacturing cables will go directly to a reference design model.
Operator, Operator
Thank you. Our next question comes from the line of Suji Desilva.
Unidentified Analyst, Analyst
Hi, Bill. Hi, Dan. I have a question about the revenue breakout, specifically for Dan. The product engineering services represent a smaller portion of the revenue, but could growth in that area indicate increased activity with hyperscalers? As we expand from one to two or three or four hyperscalers, would we expect to see growth in that revenue? Is that the correct interpretation?
Dan Fleming, CFO
I would not interpret it that way. Since the beginning, we have been able to secure some non-recurring engineering dollars from clients as we created chips and solutions tailored for them. This highlights the innovative aspect of our offerings. Over the long term, we don't anticipate significant growth in absolute dollar terms. Similar to our intellectual property revenue, it can fluctuate quite a bit from quarter to quarter. Therefore, I wouldn’t regard it as a leading indicator for anything along those lines.
Unidentified Analyst, Analyst
Thank you, Dan. Bill, regarding the Total Addressable Market for AEC, is it correct to say that it ranges from $4 billion to $5 billion? Is the bulk of that associated with hyperscalers, or is there a significant portion outside of hyperscale that could become relevant as you expand your offerings beyond your initial customers?
Bill Brennan, CEO
Yes. To clarify, I mentioned a multi-billion dollar market that forecasts indicate will develop over the next four to five years. I see the hyperscaler market as the key driver for near-term growth. However, as enterprises adopt higher speeds, there will be significant opportunities. Additionally, markets outside of what we traditionally view as hyperscalers could also make noteworthy revenue contributions. We are already working with the first 5G carriers, which are comparable in scale to hyperscalers. Looking at our various engagements that have quickly transitioned into customers, together they could contribute to our revenue as much as a major hyperscaler. In the near term, our primary focus remains on hyperscalers to drive revenue quickly, but we are also engaging with a wide range of others, which together can generate substantial revenue for us.
Unidentified Analyst, Analyst
Okay. Thanks, Bill.
Operator, Operator
Thank you. And our next question comes from the line of Vijay Rakesh with Mizuho.
Vijay Rakesh, Analyst
Yes. Hi, Bill and Dan. Just a quick question on the quarter, I know, the IP came in light, but it looks like you made it up well with the product side. Just wondering where the strength was, was it in cable or optical, if you can give us some color? And was it specific to some customers or markets?
Bill Brennan, CEO
So it was a strength in AEC as you would expect. And that has been with our lead customer that we've discussed in the past.
Vijay Rakesh, Analyst
Got it. And then on the JDM side, the joint development program, do you expect that to become a bigger mix of your distribution as you look at the calendar 2023 or fiscal 2024, would those have similar margins to your direct sales?
Bill Brennan, CEO
Definitely, when we talk about a joint development model, what we're really referring to is that the hyperscaler would be involved in the selection of the DSP or other components. Typically even under a JDM model, we would be selling to the optical module manufacturer. And so I do expect that this JDM model or if we kind of back up and we say the model where the hyperscaler gets involved in the decision-making, I expect that to be more and more popular as we go forward for Credo. If we kind of look at it from a Credo development perspective in the market, how we've been progressing. Really, our view is that, first, we succeeded engaging three JDM customers, where the end customer selected the DSP component from Credo. Now the ramp to high volume looks delayed due to the first two hyperscalers being in China, but kind of in the second phase here, we've gained traction among Tier 1s. We're talking with all of them directly on high volume deployments. And so we see multiple programs in sight on 200 to 400 the major benefit that we give is a refresh that got a better combination of performance, power, and cost. And it's becoming more important to the hyperscalers and the optical companies running high volumes. CapEx and OpEx are more and more can focus recently, and so if there's low-hanging fruit, it seems like it makes sense. And I might have mentioned in the last call, but I feel even more confident that we're going to officially engage with a Tier 1 hyperscaler in the U.S. on a 400 gig optical solution and it will include the DSP with an integrated driver, as well as the TIA. And so that's more than kind of line of sight. That's basically a few stages left to entering a contract with them. And then I would say that kind of the third phase of this is for the next generation or 800 gig, and now that we've opened up conversations, about their existing high-volume deployments. The same kind of compelling performance power and cost benefit that we offer additive to that will be the fact that we're on time. Our time to market is good for the 800 gig devices and for the 800 gig market. And so the first testing that's been done by the customer base has been very well received. So they see very clearly the performance is clearly good enough. The power is clearly good enough and the cost is compelling in a sense, because we're building in 12 nanometer versus a more advanced process like seven or five. And so given the fact that we've established market credibility through our first three engagements and the engagements that we're pursuing on existing programs, I expect the wins for 800 gig to come as the market takes off.
Vijay Rakesh, Analyst
Got it. I have a quick question. I know China is reintroducing COVID restrictions. It seems like you have resolved many of your supply constraints, as that wasn't mentioned in your comments. Can you discuss what you are doing in terms of diversifying your supply chain, perhaps regarding Vietnam or the Philippines, and how you plan to navigate these restrictions?
Bill Brennan, CEO
So I feel good about where we are today. Even if we face disruptions in China, we've signaled that we're going to build inventory. That's a surefire way of making sure that we've got the product that our customers need as they ramp. We're going to continue to be in that mode until we can land ourselves in something in a location that's not dependent on China. We've made progress in the last 90 days and my expectation is that will be in production in less than a year in alternative locations for our current supply chain. And I think that, that kind of matches with what the customer base is looking for as well.
Vijay Rakesh, Analyst
Got it. Great. Thanks a lot.
Operator, Operator
Thank you. And our next question comes from the line of Tore Svanberg with Stifel.
Tore Svanberg, Analyst
Yes. Thank you, Bill. Thank you, Dan. Congrats on the record results, I have a non-AEC related question. You talked about the UCI Express opportunity. And I do recognize that this is kind of further out, but as we think about chiplets and licensing, how should we think about this playing out for you over the next few years?
Bill Brennan, CEO
First of all, we classify chiplets as a product since we are both building and selling them. Regarding the intellectual property, our long-term guidance aligns with the 10% to 15% range that Dan mentioned. For UCIe chiplets, we were very early adopters in this area and are currently ahead of the competition. We recognized the shift towards disaggregation early on. Although it didn't materialize as anticipated, now that UCIe is approaching, we are strong proponents. Considering the consortium led by Intel and their current initiatives, chiplets are poised to become mainstream in high volumes in the near future. As speeds progress from 32 gig to 64 gig, their popularity is expected to increase. Within a server, we anticipate the future incorporation of eight to 16 chiplets, which presents a significant revenue opportunity given the projected volume.
Tore Svanberg, Analyst
That's very exciting. And then to follow-up on AEC and the sort of the second hyperscaler that's expected to launch, sounds like you have a lot of confidence in the timing there. I was just hoping you could give us a little bit more background information, I mean, obviously when we think about the hyperscalers cutting CapEx, I'm sure there's some priority CapEx and some not the priority CapEx? So I mean would this fall into like the really highest end priority for that particular customer? Is that how we should think about it?
Bill Brennan, CEO
That's the way that I think about it. For sure, I view this program as something that is a strategic imperative as they talk about it within the supply chain, as well as within our customer base. So I feel pretty confident that this is going to be mainstream. And although they have been pretty consistent with their schedule, of course, things can happen that might cause a delay. We're not seeing any signs of that and the closer we get, obviously, the more confidence we have in the ramp. But it's not as if I can make a firm commitment on exactly when they're going to go to production. But it feels like no change from our end.
Tore Svanberg, Analyst
That's very fair. Last question for Dan. Dan, you said in the last quarter you would build inventory, you did that inventory days now just over 100. Based on Bill's comment about sort of keeping building inventory until you feel better about the whole China lockdown situation, how high should we expect inventory days to potentially get to before you feel like you got the situation under control?
Dan Fleming, CFO
Well, I don't expect that the days will increase from where they are right now or if they do it would be a very small increase. We were essentially flat quarter-over-quarter. Even though it looked like a significant increase in inventory, it’s actually kind of in line with our product growth quarter-over-quarter. So bearing that in mind, we're comfortable with where we are. We continue to build an excess amount of days of inventory, of cable inventory to ensure that we don't run into a situation that we had back in Q4, when that COVID lockdown kind of interrupted our fulfillment of demand. So we're comfortable with where we are right now and I wouldn't expect any major deviation from a day's inventory perspective. Longer term, of course, that will settle down to maybe 100 days of inventory, but that's off in the future.
Tore Svanberg, Analyst
Okay. Sounds good. Congrats again. Thank you.
Dan Fleming, CFO
Thanks.
Operator, Operator
Thank you. And our next question comes from the line of Matt Ramsay with Cowen.
Lannie Trieu, Analyst
Hi. This is Lannie on for Matt Ramsay, I wanted to extend my congratulations for the quarter as well. Going back to the optical solutions, could you confirm that the push out was mostly due to your first two customers being Chinese hyperscalers? And is there any line of sight as to how long that program is where you are in terms of the qualification to product volume ramps?
Bill Brennan, CEO
Yes, I can confirm that the first two hyperscaler customers are Chinese data centers. Last quarter, we were informed that there will be a change in the timing of the deployment. I don't have exact details on when that will begin to increase. From my viewpoint, the key aspect is when we transition to high volume. Currently, we may be handling small volumes, but our main focus is on the duration of the shift to high volume. Regarding our efforts with U.S. hyperscalers, we are continuing to make progress. In fact, I believe we have gained more clarity on that, although it may take a bit longer, and I think this will also lead to higher volume.
Lannie Trieu, Analyst
Understood. That's helpful. Thank you. And I know in past earnings calls, you've mentioned a consumer customer for USB, PCIe, I believe for licensing. Any updates there that we should know about in terms of progress?
Bill Brennan, CEO
Yes. We're hip-deep in executing on that IP license, we were selected by this large consumer company as the partner for this really important next generation USB standard, which is 80 gigabits per bandwidth two lanes of 40 gig and PAM modulation. I think it's reflective of the fact that our architecture is unique. We delivered lower power than anybody in the industry. So it's really a great confirmation that they would select us as their partner. And this goes back to even four years ago that they were doing due diligence and we signed the contract finally a little more than a year ago. But yes, we're hip-deep on execution and we expect to be wrapping up the technical part of the work really within the next six months and then we'll absolutely be there as they move from their own samples to production.
Lannie Trieu, Analyst
Got it. Thank you so much.
Operator, Operator
Thank you. And our next question comes from the line of Quinn Bolton with Needham & Company.
Quinn Bolton, Analyst
Hi, thanks for taking it. A quick couple of follow-ups first. Dan, could you give us a sense your lead customer, what percent of revenue was in the quarter? I know they've been above 10% for the past several quarters? And then a follow-up for Bill, as you look to the PCIe market, wondering if that also includes opportunities is CXLs, since CXL does run on the PCIe electricals? Thanks.
Dan Fleming, CFO
Yes. So, Quinn, so what you'll see in our Q as we file it in a day or two is that we had three 10% customers in the quarter, the largest of which was 44%, then there was a 19% and 16% customer. So you can kind of fill in the blanks from there, we don't disclose the specifics of who those customers are. But in the 44% case, it's pretty obvious.
Quinn Bolton, Analyst
Yes, okay. Perfect. Thank you.
Bill Brennan, CEO
Yes, to answer your question on PCIe, we definitely include CXL, we kind of talk about that collectively.
Operator, Operator
Thank you. There are no further questions at this time. Mr. Brennan, I'll turn the call back over to you.
Bill Brennan, CEO
I'd like to thank everybody for joining the call. I appreciate all the thoughtful questions and with that, we will end the call. Thank you very much.
Operator, Operator
This concludes today's conference call. You may now disconnect.
