MC33790 : 2-Channel DSI Physical interface for bus masters

The MC33790 is a dual channel physical layer inter-face IC for the Distributed Systems Interface (DSI) bus. It connects DSI masters to DSI slave sensors and actuators. It provides power to the slave sensors and actuators over the DSI Bus and supports bi-directional communication between the slave and master ICs over this same bus wire. When used with other DSI family parts, remote sensing and control can be easily and inexpensively accomplished. Up to 30 remote devices can be supported by single MC33790. The MC68HC55 is an SPI to DSI protocol converter which is made to match the pin connections of the MC33790 and allow any MCU with an SPI to generate a DSI Bus.

MC33790 Features

Complete power source,transmitter and receiver for two independent DSI busses

Waveshaped voltage mode transmitter (reduced EMI)

Pinout matched to MC68HC55 for easy PCB layout

Independent 150 mA current limit per channel output

Logic input thresholds are 3.3 V and 5.0 V compatible
