Marvell at the Forefront of Connecting the Cars of Tomorrow, Today

By Alex Tan, Director, Automotive Solutions Group

When you sit in a car today, the focal point of the interior is likely an infotainment system. From displaying vehicle diagnostics to parking assistance to enabling multimedia streaming and additional controls such as phone calls, navigation, etc., the infotainment system has become the touchpoint of the in-vehicle connectivity experience.

In order for drivers to take full advantage of these advanced features, internal vehicle data networks need to provide high bandwidth and seamless connectivity so these technologies can effectively communicate with each other. However, with multiple in-vehicle systems using different interfaces and connectivity technologies, how can we bridge the communication to get them to speak the same language?

The IEEE’s Ethernet standards act as the connectivity backbone to seamlessly link the different domains of the car such as infotainment and Advanced Driver Assistance Systems (ADAS). Marvell is proud to have played an instrumental role in the development of the IEEE 802.3bp 1000BASE-T1 PHY standard which enables data between in-vehicle systems to be distributed over a flexible, low cost and high bandwidth network. In October 2015, Marvell introduced the 88Q2112 automotive Ethernet physical layer (PHY) transceiver, the industry’s first 1000BASE-T1 automotive Ethernet PHY transceiver based on the IEEE’s draft 1000BASE-T1 spec. Leveraging our advanced wireless and Ethernet technology solutions, the 1000BASE-T1 solution supports uncompressed HD video, ideal for distributing camera and sensor data in ADAS applications. In the infotainment space, gigabit Ethernet over a single unshielded twisted pair copper cable is a logical solution for transporting audio, video and voice data at a higher data rate and resolution. Marvell’s 88Q2112 PHY transceiver enables automakers to use one Ethernet switch to connect the multiple advanced features of tomorrow’s cars. Furthering our commitment to automotive innovation, in April 2016 we opened the Marvell Automotive Center of Excellence (ACE), a first-of-its-kind automotive networking technology development center. Located in Ettlingen, Germany, ACE aims to expand development and education efforts to advance the architecture of future connected, intelligent cars.

We showcased Marvell’s advanced auto connectivity solutions at the 2016 IEEE-SA Ethernet & IP @ Automotive Technology Day (E&IP@ATD) in Paris this past September, demonstrating how our technology supports multiple HD video streams with up to 4K resolution. Covering the exciting activities at E&IP@ATD, Tadashi Nezu of Nikkei wrote about our automotive connectivity leadership, noting that Marvell is rapidly coming to the forefront of the market. Nezu also lauded the Company for its early Ethernet development efforts, noting how Marvell quickly developed a solution compliant to the draft IEEE 802.3bp 1000BASE-T1 standard, before the specifications were even finalized.

Earlier this month, we presented our solutions at the heart of the world’s automotive development at the 3rd annual Automotive Ethernet Congress in Munich. Manfred Kunz, head of development at the ACE, spoke about automotive Ethernet security, while Christopher Mash, senior manager of automotive system architecture and field applications, co-presented with Bosch and Continental who shared their experience with the new 1000BASE-T1 technology. We showcased several automotive Ethernet solutions across nine customer booths, including the world’s first 1000Base-T1 Automotive Ethernet system, industry-leading intelligent security on the new 88Q5050 switch and a new platform demonstrating Marvell’s 10Gb capability for automotive.

The event was a success, drawing over 700 attendees, as well as speakers and exhibitors from over 20 countries.
