ST3293 - RS-422 HIGH SPEED TRANSCEIVER WITH DIGITAL EMPHASIS

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 inter symbolic interference.

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

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. Comments 50 parts per tube / 20 tube per box 2500 parts per reel SO-14 (Tube) SO-14 (Tape & Reel).

ST3293 RS-422 HIGH SPEED TRANSCEIVER WITH DIGITAL EMPHASIS s s s s s FULL DUPLEX COMMUNICATIONS DEVICE RS-422 PROGRAMMABLE EMPHASIS INCREASES THE DISTANCE AND DATA RATE HIGH SPEED: DATA RATE UP TO 25Mbps -7V TO 7V COMON-MODE INPUT VOLTAGE RANGE LVTTL LOGIC INPUT THRESHOLDS SOP 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 inter symbolic 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.
