The 33790 is a dual channel physical layer interface IC for the Distributed System Interface (DSI) bus. 33790 is designed to meetcan also be used in non automotive automotive requirements. Itapplications. It supports bidirectional communication between slaveand master ICs. Some slave devices derive a regulated 5.0V from the bus, which can be used to power sensors, thereby eliminating theneed for additional circuitry and wiring.
