MCZ33790

www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC33790 Rev 10.0, 12/2006 Two-Channel Distributed System Interface (DSI) Physical Interface Device 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.
