When you’re using your phone, tablet, or laptop, you’re likely benefiting from advancements in the MIPI M-PHY? high-speed serial communications protocol, which enables the interface between SoCs, application processors, baseband processors, and peripheral devices. The specification contributes to the ability of these mobile devices to perform with the briskness and low power consumption we’ve come to expect as we’re navigating through feature-rich apps and multimedia content. And it’s thanks to a team of savvy engineers, including 草榴社区’ Sergio Silva, that the protocol continues offering progressively faster data rates and enhanced power efficiency.

For his work advancing MIPI protocol over the years, Silva, a project director for 草榴社区 MIPI M-PHY IP, was recently presented with the MIPI Alliance’s Lifetime Achievement Award. “An active contributor [to the MIPI Alliance] for more than a decade, Silva recently brought forward a key proposal for the next version of the specification and has leveraged his profound knowledge of physical layer requirements to proactively resolve issues and challenges, and clarify M-PHY use cases,” the Alliance noted in a .

Silva knew from an early age that he would pursue a career in electronics. We recently chatted with him about his work at 草榴社区, his contributions to the MIPI M-PHY protocol, and how his roles with the MIPI Alliance and with 草榴社区 are complementary. Read on for some inspiring insights.

Q: How did you make your way to 草榴社区?

A: After CERN, I went back to Portugal and accepted an opportunity in 2011 to join 草榴社区 as a project engineering manager. I started working with a design team that was building a new PHY for a new protocol, which turned out to be MIPI M-PHY. They needed someone with expertise to participate in work groups and lead discussions and architecture decisions around the PHY.

In the past 10+ years, we’ve evolved from a relatively low-speed PHY with little impact on the market to one that has now demonstrated market success with operating speeds at the limit of consumer-grade technology. (The latest version of the spec,, features a High Speed Gear 5 (HS-G5) that enables engineers to double the potential data rate per lane to 23.32 Gbps and to 93.28 Gbps over four lanes.)

Q: What are some memorable milestones so far in your 草榴社区 career?

A: Above all, it’s gratifying to help our customers achieve tape-out of their designs and move on to successful production runs. Knowing that I played a role in evolving a specification that is enabling all of this new technology that we use everyday is also satisfying. Collaborating with my team at 草榴社区, there are a few other achievements that stand out:

• Our team developed one of the industry’s first M-PHY Type-1 IP cores at 6 Gbps for consumer devices
• We deployed M-PHY IP at 7nm, leveraging a common development infrastructure that enables our customers to reduce their development costs and risks while getting to market quickly
• We developed M-PHY IP based on the latest spec, with a data rate of 24 Gbps, which is remarkable for the consumer appliance level

Q: Discuss your role in the MIPI Alliance’s M-PHY working group.

A: Initially, I was involved in reviewing and understanding the specification. Over time, my role has evolved to making suggestions to help simplify the specification and to allow more feasible implementations. For example, as we’ve moved to higher speeds, I’ve worked with the team to propose specification solutions that allow 草榴社区 and other IP vendors to successfully implement PHY IP that support the latest data rates.

In these working groups, we have contact with a lot of customers and system implementers, discussing their needs, what they envision for the future, and what they expect to be required a year, 5 years, and even 10 years down the road. We always approach these opportunities with the mentality that we’re not just solving today’s problem. What we propose should be scalable so that we can adjust quickly to market demands.

Q: What does earning the MIPI Alliance’s Lifetime Achievement Award mean to you?

A: The award is a welcome recognition of the work I’ve been doing on the M-PHY specification. My involvement in the MIPI Alliance working group for M-PHY is something I’ve been doing in parallel with my other responsibilities at 草榴社区, and many people aren’t aware of this involvement. While all the contributions to the specification stem from team efforts, I’m honored that the hard work, time spent in meetings across different time zones, and time spent in different countries to attend meetings has been recognized.
