Micrel and Marvell Deliver World's First Standards-Compliant Ethernet PHYs for In-Vehicle Networking

[By NBC-1TV H. J Yook]Marvell (NASDAQ: MRVL) and Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance linear and power, clock and timing and LAN solutions, today announced the world's first fully interoperable IEEE 802.3 standard-compliant Ethernet PHY for in-vehicle networking. The two companies successfully demonstrated the technology at the recent Nikkei Electronics Symposium, which took place September 5, 2012 in Tokyo, Japan. With this newly proven solution, the automotive industry now can leverage the existing ecosystem of Ethernet networking applications for use in the next-generation of mission critical vehicle diagnostics, infotainment and connected-car platforms.

“As onboard networking grows more complex and more critical to an automaker‘s ability to differentiate itself, the auto industry has developed an acute need for standards-based networking solutions that can withstand the unique conditions and regulatory requirements for today’s cars. With hundreds of onboard sensors that must connect to a central computer, and with Internet-connected infotainment systems that tie into a vehicle‘s primary operating structure, it is critical that auto manufacturers can reuse IEEE standards based silicon from high-volume markets to streamline development, production and cost-effective deployment,” said Steve Dansey, vice president of Marvell’s CSI business unit. “Our work with Micrel is testimony to both companies‘ market leadership and demonstrates yet another method in which Marvell offers total connectivity solutions for the planet’s most vital platforms.”

For several years, the automotive industry has been unable to use common Ethernet protocols for onboard networking. Legacy silicon does not meet stringent automotive emissions requirements, and the development of car-specific PHYs has been historically cost prohibitive. However, Micrel and Marvell's family of standard PHYs support speeds of up to 100 Mbps and run with less power and fewer emissions -- bringing them well within the desired specifications for the auto industry. Now automakers can take full advantage of the benefits of Ethernet protocol to develop the next-generation of in-vehicle networking architecture.

“Utilizing standard IEEE technology will allow the automotive industry to take full advantage of the vast existing foundation of Ethernet networking applications,” noted Wiren Perera, vice president of Corporate Strategic Marketing, Micrel. “This new solution also provides immediate access to multiple other standards such as energy efficient Ethernet (EEE) for reduced power consumption and power over Ethernet (PoE) for transmission of power without requiring extra wires. We are very pleased to collaborate with Marvell on this ground breaking technology. Auto manufacturers now have the technology and solutions to build new systems that will change the way we drive.”

ABI Research currently predicts global connected infotainment shipments will surpass 50 million units by 2017. In the same year, IMS Research predicts camera-aided driver assistance systems alone will number 34 million. Additionally, by 2025, the GSMA predicts every car will have Internet connectivity. Micrel and Marvell's innovations in Ethernet chipsets are designed to help automakers accelerate their deployment timelines and bring to market more robust, smarter and safer and a more enjoyable driving experience to automobile drivers around the world.
