Technical Data

Dual DBUS Master with

Differential Drive and

Frequency Spreading

33780

The 33780 is a master 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 slave

devices.

DIFFERENTIAL DBUS MASTER

The differential mode of the 33780 generates lower electro-

magnetic interference (EMI) in situations where data rates and wiring

make this a problem. Frequency spreading further reduces in-

terference by spreading the energy across many channels, reducing

the energy in any single channel.

Features

• Two Independent DBUS I/Os
