FlexRay Transceiver

FlexRay is an network communications protocol used in automotives to control on-board computing. Developed by the FlexRay Consortium, FlexRay is designed to be better than CAN or TTP, but has its drawbacks in being a bit more expensive. Presently, the FlexRay standard is part of a new set of standards namely ISO 17458-1 to 17458-5.

The TJA1080A is a FlexRay transceiver that is fully compliant with the FlexRay electrical physical layer specification V2.1 Rev. It is primarily intended for communication systems from 1 Mbit/s to 10 Mbit/s, and provides an advanced interface between the protocol controller and the physical bus in a FlexRay network.
