3 Description

The DS90LV047A device is a quad CMOS flowthrough

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) using

Low Voltage Differential Signaling (LVDS)

technology.

The DS90LV047A accepts low voltage TTL/CMOS

input levels 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, disabling 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.
