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.
