Dual DBUS Leader, Differential Drive, Frequency Spread
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
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
