DESCRIPTION
The ST3293 is a high-speed RS-422 transceiver
with an emphasis circuitry on the driver which
allows reliable long distance communication at
high
data
rate
by
reducing
interference. The differential amplitude of the
ST3293 is digitally programmable in 7 steps
through 3 control pins. The emphasis reduces the
inter symbolic interference by increasing the
signal amplitude under the micro control and
counteracting the effects of the cable with the
varying data stream. The ST3293 is a full duplex
device that operates from a single +5V supply. It
inter
symbolic
features driver output short circuit current limiting
and an open circuit fail-safe receiver input. The PE
input can be used as an emphasis enable. The PE
held LOW disable the emphasis instead set to
HIGH enable the emphasis with the configuration
on C0, C1 and C2 when DI change logic level. The
DI input can direct drive the outputs with a fixed
emphasis or without emphasis as shown in the
timing diagram.
