Descriptions
The star coupler is part of the electrical, physical layer in a FlexRay communication network. The E981.56 provides interfaces to connect up to four branches of twisted pair physical bus lines to other bus drivers or star couplers. It also interfaces with a communication controller (CC). Via SPI the bus driver (BD) provides status information concerning failure detection on the bus lines (e.g. short circuit, ground loss) and over temperature condition to a host controller (HOST). An interrupt signal is generated whenever the failure status changes.The device supports normal and standby mode and provides remote wake up capability via bus line. The output (INH) can be used to control an external voltage regulator.
