DS90LV012A/DS90LT012A
3V LVDS Single CMOS Differential Line Receiver
General Description
The DS90LV012A and DS90LT012A are single CMOS differ-
ential 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
3V 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.
