MC33781: Quad DSI 2.02 Master, Differential Drive, Freq Spread

The NXP® MC33781 is a master device for four differential DSI 2.02 buses that contains the logic to interface the buses to a standard SPI port and the analog circuitry to drive data and power over the bus, as well as receive data from the remote slave devices.

特性
  • 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
