DS90LV031B
3V LVDS Quad CMOS Differential Line Driver
General Description
The DS90LV031B is a quad CMOS differential line driver
designed for applications requiring ultra low power dissipa-
tion 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 DS90LV031B 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
DS90LV031B is enhanced over the DS90LV031A in that the
inputs are further ruggedized for excessive undershoot.
The EN and EN* inputs allow active Low or active High
control of the TRI-STATE outputs. The enables are common
to all four drivers. The DS90LV031B and companion line
receiver (DS90LV032A) provide a new alternative to high
power pseudo-ECL devices for high speed point-to-point
interface applications.
