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