Auto-Ethernet Extravaganza - NXP Swallows OmniPHY

The world's largest supplier of automotive chips, NXP Semiconductors, has announced its acquisition of OmniPHY, a networking IP startup, for better bandwidth on its Ethernet solutions, for an undisclosed sum. This will complement NXP's existing products based on standards like CAN, LIN and FlexRay.

OmniPHY has been a regular on the conference trail showcasing its Automotive IP solutions and support for cars becoming "Servers on Wheels". The suffix PHY comes from the IEEE shortform for a physical layer communication protocol.

Alexander Tan is NXP's Vice President of Automotive Ethernet Solutions since May 2017, based in San Jose, California, and has Ethernet experience from Fairfield County-founded National Semiconductor (now acquired by Texas Instruments) and other firms.

CAN standard (Controller Area Network) is a vehicle bus standard that allows microcontrollers to communicate, via a message-based protocol, in applications without a host computer. Development on the CAN bus started in 1983 at Bosch, with the first chips produced by Intel and Philips. The first production vehicle to employ this technology was the Mercedes-Benz W140 in 1991.

LIN (Local Interconnect Network) is a cheaper to implement version of CAN. It was created in the 1990s by the LIN Consortium founded by five automakers (BMW, Volkswagen, Audi, Volvo, Mercedes-Benz).
