I would now like to hand the conference over to Munjal Shah, Head of Investor Relations.

Munjal Shah, Head of Investor Relations

Thank you. Good afternoon and thank you for joining us today on Synaptics’ second quarter fiscal 2022 conference call. My name is Munjal Shah and I am the Head of Investor Relations. With me on today’s call are Michael Hurlston, our President and CEO, and Dean Butler, our Chief Financial Officer. This call is also being broadcast live over the web and can be accessed from the Investor Relations section of the Company’s website at synaptics.com. In addition to a supplemental slide presentation, we have also posted a copy of these prepared remarks on our investor relations website. The supplementary slides have also been furnished as an exhibit to our current report on Form 8-K filed with the SEC earlier today and add additional color on our financial results. In addition to the Company’s GAAP results, management will also provide supplementary results on a non-GAAP basis, which excludes share-based compensation, acquisition-related costs, and certain other non-cash or recurring items. Please refer to the press release issued after market close today for a detailed reconciliation of GAAP and non-GAAP results. Additionally, we would like to remind you that during the course of this conference call, Synaptics will make forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance, and business, including our expectations regarding the potential impacts on our business of the COVID-19 pandemic and the supply chain disruption and component shortages currently affecting the global semiconductor industry. Although Synaptics believes our estimates and assumptions to be reasonable, they are subject to a number of risks and uncertainties beyond our control and may prove to be inaccurate. Synaptics cautions that actual results may differ materially from any future performance suggested in the Company’s forward-looking statements. We refer you to the Company’s current and periodic reports filed with the SEC, including our most recent Annual Report on Form 10-K, for important risk factors that could cause actual results to differ materially from those contained in any forward-looking statement. Synaptics expressly disclaims any obligation to update this forward-looking information. I will now turn the call over to Michael.

Michael Hurlston, President and CEO

Thanks, Munjal. I’d like to welcome everyone to today’s call. We finished calendar 2021 on a strong note and I am proud of what we were able to achieve. We capitalized on our market opportunities while navigating supply and logistics challenges. We delivered double-digit revenue growth in 2021 while still managing to consistently improve gross margin. Revenue for the December quarter was at the mid-point of our updated guidance, with continuing strength in our IoT products. Our GAAP and non-GAAP gross margin was another record for the company. Higher revenue and gross margin in turn drove our quarterly non-GAAP operating margin and non-GAAP EPS to record levels as well. Our momentum remains strong and we’re seeing many growth drivers, particularly in IoT applications. Our design-win pipeline remains robust, and we see continued opportunities to cross-sell our products, driving our dollars per platform higher. Our customers are introducing new digitally enhanced products that are smarter and more connected than ever. At this year’s CES show, several products such as IoT home hubs, smart cameras, wireless workplace configurations, smart doorbells, and smart monitors were announced and feature our semiconductor solutions. In early December, we completed the acquisition of DSP Group and welcomed a talented group of incredibly capable engineers. We expect the team to accelerate our product roadmaps in the areas of wireless, home security, and low power edge AI. The learning that DSP Group has had on voice-enabled AI products will serve us well as we embark on tackling the even more promising long-term opportunity applying machine learning to simple computer vision applications. Our integration is on track and we are already seeing the benefits of the two teams working together. Synaptics’ larger sales force and strong customer relationships are bringing DSP Group technology into new accounts that were not previously accessible. Meanwhile, we are seeing pull through of Synaptics’ technology, particularly wireless, on existing DSP Group platforms. Our IoT products are now at a milestone $1 billion annual revenue run-rate, growing 60% year-over-year and accounts for 62% of our total revenue. Wireless continues to be the fastest growing piece of the IoT portfolio. New sockets are being unlocked as IoT customers begin the transition to Wi-Fi 6. Wi-Fi 6 is particularly well-suited for IoT devices because it allows a greater number of products to connect to the network simultaneously without any one device being starved by other high traffic units on the same network. The technology also enables low power consumption, which is particularly critical in battery-powered IoT devices. Our competitive differentiation is strongest in high bandwidth low power applications because our Wi-Fi 6 products are 90% more power efficient compared to prior generations and 35% more efficient than the competition. We have design wins across a variety of product categories including surveillance cameras, drones, smart displays, gaming, wearables, smart speakers, and other consumer-centric devices. Our industry-first Triple-Combo wireless device is being sampled, and we expect initial revenue toward the end of the calendar year. The product is based on the Wi-Fi 6E standard enabling devices to operate at a higher frequency band where there is less congestion. We are making organic investments to grow the business, deploying new engineering resources, and are happy to report that we have now taped out two new products based on our internal efforts. With our strong momentum, we remain confident in achieving our target to double our wireless revenues again. Our Video Interface products continue to lead the market, and our latest innovations are creating distance to the field. Our newly announced wireless docking solution simplifies the work area and was demonstrated at CES this year by one of our largest customers. We are excited about the potential of this new class of product as it enables improved productivity for end-users and flexible workplace configurations for enterprises. The solution is a prime example of our ability to cross-sell multiple technologies, in this case combining our wireless connectivity, video compression, and processor expertise. In the protocol adapter and converter market, we are seeing early traction as we enter a completely new market opportunity. We have introduced two devices in recent quarters which open up that additional total addressable market, and now have a dozen or so design wins ramping over the next few quarters. Our differentiated solution is a single-chip offering that lowers power consumption by 75% and reduces overall footprint by 60%. We're seeing terrific market traction in virtual reality headsets with continued revenue growth and design win momentum. We are winning across the board including many VR manufacturers in China. Our display technology is the highest performing custom design for those headsets and is the first and only solution in the market that supports a total resolution of greater than 4K with refresh rates of 120 hertz. A high refresh rate is essential for smoothness of motion, as it allows for higher frame rates and lower latency that are both critical to ensure a more realistic VR experience. We are continuing to invest in a future roadmap that features even higher resolutions and refresh rates, as well as leading the transition to newer display technologies such as micro-OLED. The market is still in its infancy and we feel confident about our position, market potential, and the strength of our roadmap. In Automotive, we achieved our goal of $100 million in annual revenue run rate two quarters ahead of plan. Our Automotive TDDI products are now designed into more than 50 car models across 20-plus OEMs and we are seeing production ramps at six OEMs in Europe and Asia. We are very well positioned because our share of TDDI-based solutions is much higher than our share in a discrete implementation. And the market mix of these devices, though relatively small, is increasing rapidly. In fact, nearly all new designs are being initiated around TDDI technology. Moving on to our processor technology, we now have a complete suite of products that range from ultra-low power solutions that run simple machine learning models to complex high-performance video decoders that feature neural networking capability. We believe every consumer edge device will become more intelligent, driving the need for task-specific processors with artificial intelligence extensions rather than general-purpose microcontrollers. Our processors are targeted at audio and video applications, event detection, and with the addition of DSP Group low-power edge AI use cases. Our AudioSmart family of processors are being designed into headsets, tablets, smart monitors, and docking stations and boast a compelling combination of integrated voice features, noise cancellation, and low power consumption. Our video smart series combines a high-performance CPU, GPU, and neural network processing unit into a single software-enriched SoC for complex applications such as smart signage, sound bars, and video conferencing systems. Finally, our Katana processors feature the ability to run both voice and vision machine learning models at very low power levels. At CES, we announced our first significant customer Lenovo utilizing Katana in one of its tablets. We are encouraged by continuing early indicators in the low-power edge AI market and remain excited about its long-term growth prospects. Let me move on to our PC product applications. After two years of strong growth, we expect market demand in calendar year 2022 to remain at about the same level as 2021. Within that, the expectation is for commercial market shipments to be a bigger part of the mix, which plays to our strength. We are gaining share in PCs because of our technology and innovation. At CES, we launched our latest system-on-chip that enables the design of larger size TouchPads with Haptic capability. It is the first device to comply with the NIST SP800-193 standard and feature 384-bit encryption, reducing external threats on the PC. We began shipping this device in the quarter and expect all our major customers to design it in during the calendar year. Finally, in Mobile, many new models from Chinese smartphone manufacturers using our touch technology launched in the last few quarters, but it appears the end demand for some of the OEMs didn’t materialize as expected. On the other hand, we began shipping production units of our new high-end flexible OLED display driver in the quarter, which adds yet another growth vector for Synaptics. Before I conclude, let me give a quick update on our supply chain. In general, supply remains tight. In our case, the constraints are most prevalent in newer, faster-growing areas of our portfolio where new design wins are significantly outpacing any incremental supply we are getting. We expect challenges in all facets of the supply chain, wafers to back end, to persist through all of calendar 2022. To conclude, Q2 was yet another in a series of strong quarters for the company. We set multiple corporate financial records in the quarter, particularly around gross margins. Meanwhile, we continue to grow top-line revenue by both developing entirely new product categories and executing well in our core business. Now, let me turn the call over to Dean to review our second quarter financial results and provide our outlook.

Dean Butler, Chief Financial Officer

Thanks, Michael, and good afternoon to everyone. Before I begin, I’d like to remind everyone that our Q2 results and Q3 guidance include the impact of the DSP Group acquisition, which closed on December 2, 2021. Integration of this new team is well underway. We have successfully migrated all major DSP Group systems and processes to the Synaptics platform and our $30 million operating cost synergies are on track. Moving on to the fiscal second quarter results, revenue for the quarter was $421 million, at the midpoint of our updated guidance. Revenue was up 13% sequentially with strong demand for the company’s IoT products and was partly aided by the DSP Group acquisition, which includes approximately one month of contribution. Revenue from IoT, PC, and Mobile were 62%, 20%, and 18%, respectively, in the December quarter. Year-over-year, the December quarter revenue was up 18%, driven by growth in our IoT revenue, where we are continuing to focus our efforts. Our IoT product revenue increased 60% compared with the year-ago quarter and up 27% sequentially. Our revenue momentum in this area continues to outpace almost all peers and is now at a milestone $1 billion annual run-rate. Our Mobile and PC revenue declined year-over-year due to timing of certain programs. PC product revenue was down 7% sequentially and down 10% year-over-year and was impacted by continuing supply-chain shortages for certain components at our customers. Our PC demand over the last six to nine months has been relatively flat as we continue to see a stable commercial market. Our Mobile product revenue declined 3% sequentially and declined 26% on a year-over-year comparison due to a product transition with a certain customer. During the quarter, we had two customers greater than 10% of revenue at 13% and 12%. For the December quarter, our GAAP gross margin was a company record at 53.5%, which includes $19.9 million of intangible asset amortization, $4.1 million of inventory fair value adjustment, and $1.3 million of share-based compensation costs. GAAP operating expenses in the December quarter were $147.5 million, which includes share-based compensation of $35.3 million, acquisition-related costs of $10.4 million consisting of intangibles amortization and transaction costs, amortization of prepaid development costs of $2.5 million, and restructuring-related costs of $5.1 million. Our GAAP tax expense was $2 million for the quarter. In the December quarter, we had GAAP net income of $69.5 million or GAAP net income of $1.71 per share. Now, turning to our non-GAAP results. Our December quarter non-GAAP gross margin of 59.5% was a new company record and at the high end of our guidance range, reflecting a continued strong mix as we prioritize our highest value products while passing through changing input prices. December quarter non-GAAP operating expenses were at the low end of our guidance at $94.2 million, and up $5.8 million from the preceding quarter due to the inclusion of DSP Group. Our non-GAAP operating margin of 37% in the quarter was another record for Synaptics. Non-GAAP tax expense was $18.1 million for the quarter. We had record non-GAAP net income in the December quarter of $132.8 million, which is an increase of 22% from the prior quarter and an increase of 58% from the same quarter a year ago; non-GAAP EPS per diluted share was $3.26 as our focus on profitable growth continues to drive positive earnings for our shareholders. Now turning to the balance sheet. We ended the quarter with $574 million of cash, cash equivalents, and short-term investments on hand, an increase of $227 million from the preceding quarter as a result of strong cash flow from operations of $122 million and the inclusion of cash & investments which was acquired as part of the DSP Group transaction. Receivables, at the end of December, were $312 million and days of sales outstanding were 67 days, up slightly from 65 last quarter. Our days of inventory were 70, up from 51 last quarter and ending inventories were $133 million. This includes an increase in work-in-progress inventory as we pipeline material for our growing revenue projections and the inclusion of DSP Group inventory, which includes the purchase price accounting step-up. Normalizing for DSP Group, inventory days would be approximately 60 at quarter end. Despite this sequential increase, we expect inventory to remain low given our revenue and shipping forecasts while our supply chain constraints continue to depress inventory below our desired level. Capital expenditure for the quarter was $8.5 million and depreciation was $6.4 million. We anticipate revenue for the March quarter to be in the range of $450 million to $480 million. Similar to last quarter, our backlog at the start of the quarter was above the high end of our guidance range as we are still supply constrained, limiting our ability to service our customers’ full demand. Further, our demand signal continues to be strong as our backlog position has expanded and is now higher than it was when we last met one quarter ago, excluding any M&A-related backlog adds. We expect our revenue mix from IoT, PC, and Mobile products in the March quarter to be approximately 63%, 19%, and 18%, respectively. We anticipate our IoT products growing almost 100% on a year-over-year basis at the midpoint, significantly faster than the broader market and faster than all of our IoT-focused peers. We expect our GAAP gross margin for the March quarter to be in the range of 52.5% to 53.5%. We expect our GAAP operating expenses in the March quarter to be in the range of $159 million to $166 million, which includes acquisition-related charges for intangibles and transaction costs, prepaid development cost amortization, share-based compensation, and restructuring costs. Finally, our GAAP net income per share for the March quarter is expected to be in the range of $1.25 to $1.55. Now, non-GAAP outlook for our March quarter. We expect our non-GAAP gross margin momentum to continue into the March quarter. We expect non-GAAP gross margin in the range of 59.5% to 60.5%, which at the mid-point of 60% would be a notable milestone achievement and representing one of the greatest gross margin expansion success stories across the semiconductor industry. We expect to continue prioritizing our focus and delivery to a robust and positive mix while continuing to navigate supply chain constraints and changing input prices. We expect our non-GAAP operating expenses in the March quarter to be in the range of $104 million to $108 million, an increase from the December quarter as we now add a full quarter of expenses related to DSP Group acquisition, while continuing to self-fund our organic growth opportunities. We expect our non-GAAP interest expense to be approximately $8 million in the March quarter. As a reminder, our interest expense is higher due to the debt financing related to closing the DSP Group acquisition. We expect our long-term non-GAAP tax rate for fiscal 2022 to continue to be in the range of 11% to 13%. Non-GAAP net income per diluted share for the March quarter is anticipated to be in the range of $3.40 to $3.70 per share on an estimated 41 million fully diluted shares. This wraps up our prepared remarks. I’d like to now turn the call over to the operator to start the Q&A session.

Q - Raji Gill, Analyst

Yes, thank you and congratulations on stellar results. Question on the IoT. The growth that you saw in the quarter 60% year-over-year and the growth that you're expecting in the March quarter up 100%. I'm wondering if you could maybe describe some of the subsegments of IoT which are driving the growth. For instance, last quarter you mentioned virtual reality headsets adding to the IoT number you're talking about automotive growing kind of faster wireless connectivity. I'm just curious how you would kind of segment those particular areas within IoT and how we think about those segments not only in the March quarter but kind of progressing throughout fiscal year 2022?

Michael Hurlston, President and CEO

Yes, Raji, I believe your question highlighted the three main growth drivers I would identify. First, there are the VR goggles. We have a significant customer in that market that is performing very well, and as we mentioned in our prepared remarks, we are gaining traction universally, with Chinese goggles also coming online and generating good volumes. We are optimistic about that. The second area you mentioned is automotive. The transition here involves moving from discrete chips for touch and display drivers to TDDI. While we have participated in discrete touch and display drivers, our market share there was relatively low. However, as the market shifts toward TDDI, we hold a strong market share, and we believe that as TDDI becomes the dominant technology, our performance will improve significantly. Lastly, the wireless products you've referenced are another success area for us—specifically, our Wi-Fi-Bluetooth combos and our standalone GPS products, which are contributing significantly to our results. These are the three primary areas of growth. Additionally, our other businesses are performing well, and there isn't a single area in our IoT portfolio that I would identify as weak.

Raji Gill, Analyst

And that's excellent to hear. And then on the supply situation, last time we spoke the supply situation remains tight. You are in the process of consolidating your foundry partners. You had mentioned in the past that you had as many as 10 foundry partners, but you're in the process of consolidating those to a few. So I wanted to get an update in terms of, how you're looking broadly at your supplier relationship. Are you getting – are you confident that you'll get the extra capacity as the year goes on? And are you going to be able to get capacity for some of the new products and the new areas that you're focusing, first, the Wi-Fi protocol chips versus the more mobile-oriented chips?

Michael Hurlston, President and CEO

Yeah. Again, excellent question Raji, I say the following. I mean, certainly we feel like we can get incremental supply that supports the guidance and keeps us optimistic about the future; that said, you're absolutely right. We touched on it in the prepared remarks. Our biggest challenges are all these new growth areas for us because our demand is outstripping our ability to get incremental supply. So I think Dean talked about even some backlog accumulation in his remarks, and we see that in Wi-Fi. We see that in the VR goggles. We see that in automotive. We see that in these protocol adapters. So in all of these areas, where we've got effectively new categories of products, we're having the most difficulty keeping up with supply. But we are able to get incremental supply here and there, and that gives us some confidence that we're going to be able to continue on this growth vector that we've outlined.

Raji Gill, Analyst

Great. And just one more question, if I could squeeze in, and I'll step back in the queue. The gross margins 60% just phenomenal margin expansion in the last couple of few years. The 60% margin for March, could you talk about what's driving that both on a fundamental basis. Perhaps you can talk about the contribution that DSP is having. But even putting aside DSP, it does imply that the margins within the different segments IoT mobile PC have been improving. Obviously, the next question is how much of that is price increases? I know you talked about that you're passing the input cost in the form of price increases. So I would assume that would be neutral to the margins. But can you discuss how price is affecting your margins if at all? Thank you.

Dean Butler, Chief Financial Officer

Yeah, Raji. So, on pricing, what I'd say that's largely margin neutral. I mean, where input pricing has gone up certainly, we've had the price pass it along to many of our end customers. But it should be thought of as margin-neutral. Really, the margin increase as we guide into the March quarter is all around mix. So one, as our IoT portfolio continues to grow, those are a number of product areas that actually are margin accretive for us. But all areas of the portfolio have been improving their margins over time, as really our focus has been on selling the premium versions of products in all of the market areas. So, the more premium devices in PC, we're going after premium things in mobile, and of course many of the premium areas in IoT. And so that's sort of been our fundamental shift really over the last couple of years, and that's what you're seeing here going into March.

Raji Gill, Analyst

Great. Thank you very much.

Michael Hurlston, President and CEO

Thanks, Raji.

Operator, Operator

Thank you. Our next question comes from Christopher Rolland with Susquehanna. Your line is open.

Unidentified Analyst, Analyst

Hi. This is actually Doug Son on for Chris. And thank you for taking my question. So, I just want to follow up on the supply question earlier. You said your number one constraint is around the wafers. And we've actually seen some other companies either investing heavily into CapEx or just locking in wafers way in advance. So is this something that you're considering, and if you could just elaborate a bit more on your strategy here. Thank you.

Michael Hurlston, President and CEO

We are definitely looking into entering long-term agreements to secure our supply where it makes sense, but this approach is not applied universally. Our primary strategy has been to collaborate with key partners to gradually increase our wafer supply. As a fabless semiconductor company, we are not directly affected by capital expenditures; instead, we focus on consumer costs, which adds a layer of complexity to our efforts. We are continuously working to enhance our supply, and in certain circumstances, we will consider long-term agreements if the opportunity arises.

Unidentified Analyst, Analyst

Great. And then as a follow-up you also talked about the Chinese handset market being weaker than expected. So how are you seeing this end market demand here into the back half of the fiscal year?

Michael Hurlston, President and CEO

Yeah. I mean, obviously, mobile is now a smaller part of our portfolio. We certainly believe in our roadmap. We're winning the majority of our touch sockets. We feel good about our position both in Korea and in China, as I think we've talked to in previous calls. It's then what's the sell-through. And that's obviously harder for us to determine. There seems like there's some softness. But for us it's a smaller part of the portfolio now. I think Dean talked about it being sub-20% of the overall mix. I'd say on the upside, we've got this new launch of our OLED display driver. Dean talked about it a minute ago in his comment. In general and mobile we're trying to go after the very highest end of the market. And this is a good example of it. It's a very high-end OLED display driver. And so, now, in each handset we have an opportunity and particularly at the high end to sell more content per phone.

Unidentified Analyst, Analyst

Thank you.

Operator, Operator

Thank you. Our next question comes from Derek Soderberg with Colliers Securities. Your line is open.

Derek Soderberg, Analyst

Hi guys. Thanks for taking my questions. Actually, I want to start with ULE. You have some nice large service provider wins in the U.S. and Europe. Just curious how that ecosystem build-out is progressing. And wondering, what's the best path to build out that ecosystem? Is it to sort of integrate ULE into other chipsets or simply cross-selling? What's sort of the best path for driving growth in ULE?

Michael Hurlston, President and CEO

Good question. It depends on the ecosystem's direction. We are at the initial stage of our engagement with a specific customer in North America. There is potential to implement ULE-only technology in endpoint devices like window and door sensors, as this technology is suitable for long-range, low-bandwidth applications. Ultimately, I believe these sensors will be exclusively ULE. However, opportunities to combine technologies exist in the hub that controls all the endpoints, and there are possibilities in areas like surveillance cameras. In the initial phase, we are focusing on cross-selling our Wi-Fi and Bluetooth combinations into these markets. As the market evolves, we will assess whether to integrate ULE into a more advanced chip to create a strong offering. However, I doubt that the highest volume will consist of a combination solution, as single-function sensors typically serve window break and door open/close applications.

Derek Soderberg, Analyst

Got it, got it. As my follow-up there's been some data out there that a good portion of growth has been from inventory build. Obviously for you guys in the March quarter, it looks like it's going to shape up nicely. But beyond that, do you have any visibility into sell-through for IoT and PC? I think you mentioned some softness in mobile. Any visibility into channel inventories of some of your larger customers? And how are you factoring any of that into internal expectations for the year? Anything on that would be great.

Dean Butler, Chief Financial Officer

Yeah, Derek I would say, we have probably limited visibility into individual end customers' inventory positions. But what I can say is within our channel partners, the inventory remains very low. We don't really see inventory buildup in any specific area. I think the one exception is in mobile that you touched on. That actually has recently weakened for us. Outside of that, we don't see anything specific in IoT. PC continues to have occasional match set issues. I think you've heard from others around that. But that doesn't look like inventory to us. It just is an up and down on how they pull that inventory through to their factories.

Derek Soderberg, Analyst

Got it. Thanks guys.

Dean Butler, Chief Financial Officer

Yeah.

Operator, Operator

Thank you. Our next question comes from Anthony Stoss with Craig-Hallum. Your line is open.

Anthony Stoss, Analyst

Hi everyone. Congratulations on the impressive improvement in gross margin from 40% to roughly 60% in just two years. Michael, the growth in IoT has been phenomenal. How much of that growth is due to content expansion or gaining market share? Additionally, where do you envision content heading as you introduce more products in that market? Dean, I would appreciate your insights on supply constraints. What is your perspective on the June quarter? Do you anticipate it being seasonal, above, below, or in line? Thank you.

Michael Hurlston, President and CEO

Certainly. Regarding the IoT business, we've identified growth opportunities in wireless, VR, and automotive sectors. Our primary source of growth is in new categories, especially as we enter new areas like automotive where we're advancing our TDI solution. This focus is driving revenue growth. In our established core businesses, we believe we're gaining historical market share. Our video interface segment is performing exceptionally well and is a key part of our business. Overall, the main driver of growth will be these emerging categories that are creating new revenue streams for us.

Dean Butler, Chief Financial Officer

And Tony on your second question, which was around supply constraints maybe beyond the March quarter, we're sort of not taking questions beyond March at this point. But what I would say, sort of looking out our supply constraints are certainly a concern for us. We would certainly take more if we could get it from our suppliers. But the backlog is extremely strong. In fact, backlog as we sit here today, is actually higher than what it was a quarter ago. So you can sort of read that as sort of net new orders coming in are outstripping shipments going out. And then despite having a great December quarter and despite now with this guidance in the March quarter, that continues to be strong. So we're sort of sitting here and not concerned as we look out beyond March.

Anthony Stoss, Analyst

Okay. Then if I could have a quick follow-up with Michael. Shifting gears a little bit into the auto side. You guys have recently entered on the connectivity side. I'm curious, if you can share any details on the traction you're seeing or really anything in auto?

Michael Hurlston, President and CEO

Yes, Tony. I mean I think that's not quite right. We're obviously looking at connectivity for auto but we haven't entered there. Our focus has been on a lot more of these video transfer types of products, wearable products, consumer gadgets of different varieties. Automotive remains something we feel like we could go into if we want to, but at this point, we're more in kind of a look-through the window type of mode.

Anthony Stoss, Analyst

Got it. Great. And thank you.

Michael Hurlston, President and CEO

Thanks, Tony.

Dean Butler, Chief Financial Officer

Thanks, Tony.

Operator, Operator

Thank you. Our next question comes from Karl Ackerman with Cowen. Your line is open.

Karl Ackerman, Analyst

Yes. Good afternoon. Two questions for me please. One for Michael, and one for Dean. Michael, you spoke about now shipping OLED display drivers, which complements your OLED touch controller offering. I'm curious how you think about integrating both of those components that may allow you to broaden your mobile offering to new and past significant customers?

Michael Hurlston, President and CEO

Yes, Karl. We've discussed this before. When I first arrived, we mentioned a mobile TDDI product for high-end OLED phones. As we delved deeper, we recognized a significant opportunity in OLED discrete display drivers rather than pursuing a TDDI solution. Currently, most of our focus is on a line of discrete display drivers. We are still exploring TDDI, but our engineering efforts have prioritized discrete drivers because we see a faster path for entry and a better process alignment between the touch circuit and the display driver. New products are emerging, including folding and flipping displays, which require refined display drivers. Therefore, our efforts are concentrated there, even though I believe we will eventually merge the two technologies.

Karl Ackerman, Analyst

Understood. Thank you. Dean, this is the first time you gave the number of car models you're designed into, if I'm correct. Are all these models ramping today, or is there a way to think about the step function of how they will ramp over this year and next? Thanks.

Michael Hurlston, President and CEO

Yes, Karl. I mean, let me just explain the numbers that we gave. I think, we said we're designed into 50-plus models at 20 different discrete manufacturers, six of those are ramping now, so there's a lot that's future. Their design-ins, design wins, they're not production. And we really tried to characterize this market as really being in the early innings of a shift to TDDI. Most of the units that go out today are still discrete display driver, discrete touch, but we're starting to see that tipping point. And certainly, as I said in the prepared remarks, most if not all new designs are TDDI-based rather than discrete-based.

Dean Butler, Chief Financial Officer

And just one quick data point for you Karl. We have previously talked about sort of 40-plus models. And sort of the update here is now it's 50. So, it's incrementally adding our model count that we have previously.

Karl Ackerman, Analyst

Helpful. Thank you.

Operator, Operator

Thank you. Our next question comes from Kevin Garrigan with Rosenblatt Securities. Your line is open.

Kevin Garrigan, Analyst

Hi, guys. This is Kevin Garrigan on for Kevin Cassidy. Thanks for taking my questions and let me echo my congrats. My first one there's an expected inflection point coming in the second half of calendar 2022 for new Android smartphone launches. Can you give us an idea of what the adoption rate of flexible OLED is for these new smartphones? And has the competitive landscape changed in the flexible OLED touch market lately?

Michael Hurlston, President and CEO

Yes. I think our sense is that the number of flexible OLED displays are increasing, and increasing I'd say not dramatically, but something short of that. So the mix is definitely going to a flexible OLED, we continue to have strength and advantage in flexible OLED touch controllers. So as the market tips that way we feel pretty good. And then as we've characterized the second driver in our mobile business is the shift from Korean displays to Chinese displays. And there in the Chinese displays, we think we have the opportunity to sell in that display driver, again, it's the kind of the highest end of the SKU stack.

Kevin Garrigan, Analyst

Got it. That's helpful. And just as a follow-up, you guys announced the wireless docking station reference design. Can you give us a sense of what the dollar content increase is for you in a wireless docking station versus wired and should we kind of view this product as cannibalistic to your current product line, or is it kind of more market expansion?

Michael Hurlston, President and CEO

Yes. I mean, I'd say, it's a little bit of both. I definitely think there's going to be some cannibalization, but we also think it's got features to open up a whole new market set. So I think it's a bit of both. And then I think on the second one, we're looking at tens of dollars on the content side that steps up from a traditional wire dock to go to one of these wireless docks. So I don't know the exact numbers, but it's something north of 10.

Kevin Garrigan, Analyst

Okay. Perfect. That’s very helpful. Thanks guys and congrats.

Michael Hurlston, President and CEO

Thank you.

Dean Butler, Chief Financial Officer

Thanks, Kevin.

Thank you. Our next question comes from Martin Yang with Oppenheimer. Your line is open.

Martin Yang, Analyst

Hi, good afternoon. Thanks for taking the question. I have one question for Dean. Can you maybe talk about the GAAP gross margin trend in the past quarter and also being in the guidance. It feels like it's a tad lighter than your previous guidance for the December quarter and March is another slight step down. How much should we read into this – and what are the reasons behind that GAAP margin trend?

Dean Butler, Chief Financial Officer

Yes, good question, Martin. So the first thing to know is notable that the GAAP gross margin for the December quarter is actually a record as well for Synaptics. So it's trading sort of in line record on the non-GAAP and GAAP side at the same time. The December and even more so into the March guide for the GAAP gross margin is going to be highly influenced by the DSPG acquisition. So there are a number of inclusions on GAAP-related step up in inventory value intangible amortizations that will run through the GAAP-only side. So you're going to see that effect for a couple of quarters until you get through sort of that initial amortization schedule.

Martin Yang, Analyst

Got it. That’s perfect. Okay. Thank you.

Dean Butler, Chief Financial Officer

Yes. Thanks, Martin.

Operator, Operator

Thank you. And our next question comes from Brett Simpson with Arete Research. Your line is open.

Brett Simpson, Analyst

Yes. Thanks very much. I wanted to ask about the non-GAAP gross margins. You mentioned this has like been a – one of the bigger jumps in the history of the semis industry and in terms of the performance gains. And it's been a fantastic improvement over the last few years. When I look at the portfolio you offer, there's still a lot of – are you playing in a lot of consumer areas where generally the returns are structurally lower than we would normally see. And certainly a lot of your peers would have lower gross margins. And so my question is the performance of the business has been fantastic. And – but really how sustainable are the gross margin returns across the business particularly some of the new categories that you highlight start to mature? Thanks.

Michael Hurlston, President and CEO

Yes. I mean maybe I'll take the first comment and then turn it over to Dean. Obviously, we feel good about the sustainability of the gross margin line. I think mostly because while you're right the end markets in which we play are consumer auto where there's quite a bit of competition, we feel like we've got a level of differentiation, a level of integration, and a level of performance enhancement that gives us the ability to sell at higher ASPs than our competitors. We really do feel like the gross margin is something we worked on. We worked on structurally since Dean and I got here and we've obviously improved in almost every quarter we've been together. It's going to level off at some point. I mean there's no question. It's not going to improve at the rates we've seen. But I do think that it's something that's sustainable.

Dean Butler, Chief Financial Officer

Yes. Brett, I think that's the important point to take across is that largely our products are aimed at premium portions of our end markets sort of just broadly characterizing as consumer and low margin is not necessarily a true fact. In fact, we talked about – and for instance our areas of processors right? We're going after things that are doing AI at the edge, video transport, decode-encode audio with high-end features, wireless connectivity, Wi-Fi 6 and 6E that's the cutting-edge Wi-Fi standard today with lower power than any of the competitor solutions on the marketplace, unique capabilities to transport video in a wired form factor. Even in PC and mobile, we go after high-end commercial laptops. We're now integrating haptics-type designs into some of our PC products. On the mobile side again it's aimed at flagship high-end flexible OLED type mobile devices where in fact the engineering is valued and the things that Synaptics can bring is valued by the customer base and therefore we can extract a reasonable gross margin. So I think that's the way to think about it Brett. It's not necessarily sort of overly generalizing but you think about it as the premium areas.

Brett Simpson, Analyst

Okay. Thanks for that. And maybe just a follow-up on pricing. I guess, we've seen big foundries. TSMC is one of your big foundries. They've been raising prices quite meaningfully going into 2022. And we're seeing a lot of chipmakers are passing that on as they should if they can. Can you maybe talk about or give your perspective on how you're dealing with those cost increases? And when you look at that March quarter guide, how much of that sales increase is generally a pricing increase? Thanks.

Dean Butler, Chief Financial Officer

Yeah. So we're no different from many of our peers. And I think we've been pretty straightforward that we have seen input prices change in the past quarter, quarters before that. And we've incorporated any known pricing changes for our March quarter guide. We do pass along these price increases largely to our end customers. And so as input prices change largely that ASP changes in conjunction. And it is actually an economics 101, right, when demand outstrips supply you actually will see this phenomenon. So, yeah, we have been successful in passing that along and we continue to do so if input prices were to continue to change. But it's fully incorporated into our March guide.

Brett Simpson, Analyst

Got it. Thanks very much.

Dean Butler, Chief Financial Officer

Yeah. No problem, Brett.
