FlexRay transceivers
Drawing on our extensive IVN experience to take the lead in the emerging FlexRay networking protocol, we can give our customers early access to dedicated FlexRay chipsets.
A member of the FlexRay consortium, NXP is aiding development of the future communication protocol that will be at the heart of all critical in-car control systems. The resulting time-triggered, high data-rate networking solution will easily handle the increasingly large array of sensors and actuators found in high-performance IVN applications.
As NXP’s first silicon solution for the FlexRay electrical physical layer, the TJA1080(A) transceiver chip highlights FlexRay’s power and versatility. Offering an extensive feature set, excellent EMC performance and the capability to be used in node as well as in active star configurations, the TJA1080(A) is helping drive this new advanced communications system into today’s cars.
