Two-Channel Distributed System
Interface (DSI) Physical Interface
Device
The 33790 is a two-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 nonautomotive 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.
