DS90LT012AH
High Temperature 3V LVDS Differential Line Receiver
General Description
The DS90LT012AH is a single CMOS differential line re-
ceiver 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) tech-
nology
The DS90LT012AH accepts low voltage (350 mV typical)
differential input signals and translates them to 3V CMOS
output levels. The DS90LT012AH includes an input line ter-
mination resistor for point-to-point applications.
The DS90LT012AH and companion LVDS line driver
DS90LV011AH provide a new alternative to high power
PECL/ECL devices for high speed interface applications.
