ST3293 Datasheet (ST Microelectronics) - RS-422 HIGH SPEED TRANSCEIVER WITH DIGITAL EMPHASIS

ST3293, RS-422 HIGH SPEED TRANSCEIVER WITH DIGITAL EMPHASIS

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 inter symbolic interference.

The differential amplitude of the ST3293 is digitally programmable in 7 steps through 3 control pins.

ST3293 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
