With OEMs racing to offer connected car services, Marvell has developed a new Ethernet reference platform integrated with TE Connectivity's (TE) MATEnet modular and scalable connectors for automotive Ethernet, to enable a faster time-to-market for Gigabit Ethernet in automotive systems. The new development platform supports audio bridging (AVB) switching solutions with 100BASE-T1 and 1000BASE-T1 Ethernet physical layer (PHY) capability. Manufacturers are now able to quickly prototype automotive systems with Gigabit Ethernet for electrical and electronic architectures.

The next generation of vehicle technology requires a high-speed, resilient data infrastructure that can operate in the robust conditions of the automobile. Applications such as autonomous driving, advanced safety features and immersive infotainment systems are driving these new architectures. Combining Marvell's expertise in network and Ethernet, with TE's experience in providing real world automotive connector and cable systems, this development platform allows vehicle architects to begin designing these systems for mass production.

This new reference platform includes support for the AVB networking standards of the AVnu Alliance's certification test subgroup and also supports Stream Reservation Protocol to provide end-to-end management of resource reservations for automotive data streams. In addition, Marvell's Ethernet PHY transceivers (88Q2112 100BASE-T1 PHY and 88Q1010 100BASE-T1 PHY) enable high definition and uncompressed video, high speed links, between domains to support connected and autonomous driving systems and the fastest system bring up from power down. Additional features and benefits include time sensitive networking technology to support time critical control applications, vehicle-to-vehicle Wi-Fi communication to improve safety and reduce response times using real time alerts regarding traffic and road alerts. The 88Q2112 is the industry's first 1000BASE-T1 automotive Ethernet PHY transistor that is compliant with the draft IEEE 802.3bp 1000BASE-T1 standard.

Marvell's commitment to extend connectivity to the automobile includes a number of solutions to meet the needs of designers for the cars of the future.
