MC33780: Dual DBUS Leader, Differential Drive, Frequency Spread

The NXP^® MC33780 is a leader device for two differential DBUS 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 follower devices.

• The differential mode of the MC33780 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 channels, reducing the energy in any single channel
