DS90LT012AQMF/NOPB Electronic IC Chip Automotive LVDS Differential Line Receiver

DS90LT012AQ

Automotive LVDS Differential Line Receiver

General Description

The DS90LT012AQ is a single CMOS differential line receiver 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 DS90LT012AQ accepts low voltage (350 mV typical) differential input signals and translates them to 3V CMOS output levels. The DS90LT012AQ includes an input line termination resistor for point-to-point applications.

The DS90LT012AQ and companion LVDS line driver DS90LV011AQ provide a new alternative to high power PECL/ECL devices for high speed interface applications.
