FlexRay is a serial, deterministic bus system for real-time control applications. It is designed for future requirements of in-vehicle control applications, providing data transmission rates up to 10 Mbit/s. FlexRay is designed for collision-free data communication. The nodes do not arbitrate and the FlexRay Communication Controller (CC) guarantees a collision-free bus access during normal operation. The FlexRay bus system is patent-protected by the international FlexRay consortium. The consortium defines and publishes the requirements for FlexRay bus systems, for the data-link layer, the physical layer and all other requisite application layers. The TLE9221SX FlexRay transceiver is a FlexRay bus driver (BD) and it accomplishes the physical interface between the Communication Controller and the bus medium. Fully compliant with the FlexRay Electrical Physical Layer Specification, version 3.0.1 (acronym EPL).
