NXP Semiconductors is collaborating with TTTech to jointly develop automotive Ethernet switch solutions supporting OPEN Alliance BroadR-Reach Ethernet PHY technology.

Under the agreement, TTTech will provide its automotive Ethernet switch IP, while NXP implements the IP into Ethernet switch solutions with integrated PHY.

The switch chip will be specifically designed for the automotive market, but will also be suitable for various demanding industrial real-time applications, said NXP.

The jointly developed switch chip will enable applications with unshielded twisted pair cabling with BroadR-Reach PHY technology. It is the first Ethernet switch chip with three incorporated traffic classes including standard Ethernet traffic for diagnostics and ECU flashing, asynchronous rate-constrained traffic for audio/video streaming and sensor fusion, as well as synchronous traffic for hard real-time control and fail-operational systems. Hence, this new automotive switch chip will enable unified Ethernet networks and the convergence of critical and non-critical application data streams on one single network.

NXP, with its strategic focus on the connected car, has been working with industry partners to establish BroadR-Reach as an open, de facto standard for in-vehicle Ethernet. As the first automotive semiconductor vendor to licence Broadcom's BroadR-Reach technology to develop an Ethernet PHY, NXP is taking the next step towards an integrated Ethernet switch chip in close cooperation with TTTech.

"We look forward to working closely with TTTech, as we jointly develop an innovative automotive Ethernet switch solution," said Toni Versluijs, VP and General Manager, In-Vehicle Networking Product Line, NXP Semiconductors. "We believe the value proposition of TTTech's Ethernet IP together with NXP's proven technology for the connected car will lead to compelling automotive solutions for our customers."

NXP expects its sample to be out in 2014, with the final product available in 2015.
