The NXP® MC33781 is a
leader 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 follower devices.
The differential mode 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
