Technical Data

Two Channel Distributed

System Interface (DSI) Physical

Interface Device

33790

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. This device is powered by

SMARTMOS technology.
