DS90LV012A/DS90LT012A
3V LVDS Single CMOS Differential Line Receiver
General Description
The DS90LV012A and DS90LT012A are single CMOS dif-
ferential 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, short-
ed, 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 in-
cludes 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.
