DS90LV028A
3V LVDS Dual CMOS Differential Line Receiver
General Description
The DS90LV028A is a dual CMOS differential line receiver
designed for applications requiring ultra low power dissipa-
tion, low noise and high data rates. The device is designed to
support data rates in excess of 400 Mbps (200 MHz) utilizing
Low Voltage Differential Signaling (LVDS) technology.
The DS90LV028A accepts low voltage (350 mV typical) dif-
ferential input signals and translates them to 3V CMOS out-
put levels. The receiver also supports open, shorted and ter-
minated (100 ) input fail-safe. The receiver output will be
HIGH for all fail-safe conditions. The DS90LV028A has a
flow-through design for easy PCB layout.
The DS90LV028A and companion LVDS line driver provide a
new alternative to high power PECL/ECL devices for high
speed point-to-point interface applications.
