The 33781 is a master device for four differential DSI 2.02 buses. It contains the logic to interface the buses to a standard serial peripheral interface (SPI) port and the analog circuitry to drive data and power over the bus, as well as receive data from the remote slave devices.


The differential mode of the 33781 generates lower electromagnetic interference (EMI) in situations where data rates and wiring make this a problem. Frequency spreading further reduces interference by spreading the energy across many frequencies, reducing the energy in any single frequency.

 

Tools: Limited Evaluation boards available; contact sales.


Features

  • Four independent differential DSI (DBUS) channels
  • Dual SPI interface
  • Enhanced bus fault performance
  • Automatic message cyclical redundancy checking (CRC) generation and checking for each channel
  • Enhanced register set with addressable buffer allows queuing of 4 independent slave commands at one time for each channel
  • 8- to 16-Bit messages with 0- to 8-Bit CRC
  • Independent frequency spreading for each channel
  • Pseudo bus switch feature on channel 0
