DS90LV031A

3V LVDS Quad CMOS Differential Line Driver

General Description

The DS90LV031A is a quad CMOS differential line driver de-

signed for applications requiring ultra low power dissipation

and high data rates. The device is designed to support data

rates in excess of 400 Mbps (200 MHz) utilizing Low Voltage

Differential Signaling (LVDS) technology.

The DS90LV031A accepts low voltage TTL/CMOS input lev-

els and translates them to low voltage (350 mV) differential

output signals. In addition the driver supports a TRI-STATE®

function that may be used to disable the output stage, dis-

abling the load current, and thus dropping the device to an

ultra low idle power state of 13 mW typical.

The EN and EN* inputs allow active Low or active High con-

trol of the TRI-STATE outputs. The enables are common to

all four drivers. The DS90LV031A and companion line re-

ceiver (DS90LV032A) provide a new alternative to high

power psuedo-ECL devices for high speed point-to-point in-

terface applications.
