2 Description

The DS90LV012A and DS90LT012A are single CMOS

differential line receivers designed for applications

requiring ultra low power dissipation, low noise, and

high data rates. The devices are designed to support

data rates in excess of 400 Mbps (200 MHz) utilizing

Low Voltage Differential Swing (LVDS) technology

The DS90LV012A and DS90LT012A accept low

voltage (350 mV typical) differential input signals and

translates them to 3-V CMOS output levels. The

receivers also support open, shorted, and terminated

(100Ω) input fail-safe. The receiver output will be

HIGH for all fail-safe conditions. The DS90LV012A

has a pinout designed for easy PCB layout. The

DS90LT012A includes an input line termination

resistor for point-to-point applications.

The DS90LV012A and DS90LT012A, and companion

LVDS line driver provide a new alternative to high

power PECL/ECL devices for high speed interface

applications.
