Dual DBUS Master with
Differential Drive and
Frequency Spreading
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.
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.
