DS90LV047A

3V LVDS Quad CMOS Differential Line Driver

General Description

The DS90LV047A is a quad CMOS flow-through differential

line driver designed 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 DS90LV047A 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

DS90LV047A has a flow-through pinout for easy PCB layout.

The EN and EN* inputs are ANDed together and control the

TRI-STATE outputs. The enables are common to all four

drivers. The DS90LV047A and companion line receiver

(DS90LV048A) provide a new alternative to high power

psuedo-ECL devices for high speed point-to-point interface

applications.
