Automotive LVDS Differential Line Receiver
General Description
The DS90LT012AQ is a single CMOS differential line receiver
designed for applications requiring ultra low power dissipa-
tion, low noise, and high data rates. The devices are designed
to support data rates in excess of 400 Mbps (200 MHz) uti-
lizing Low Voltage Differential Swing (LVDS) technology
The DS90LT012AQ accepts low voltage (350 mV typical) dif-
ferential 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.
