DS90LV032A 3V LVDS Quad CMOS Differential Line Receiver
July 1999
General Description
The DS90LV032Ais a quad CMOS differential line receiver
designed for applications requiring ultra low power dissipation 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 DS90LV032Aaccepts low voltage (350 mV typical) differential input signals and translates them to 3V CMOS output levels. The receiver supports a TRI-STATE
may be used to multiplex outputs. The receiver also supports
open, shorted and terminated (100Ω) input Fail-safe. The receiver output will be HIGH for all fail-safe conditions.
The DS90LV032A and companion LVDS line driver (eg.
DS90LV031A) provide a new alternative to high power
PECL/ECL devices for high speed point-to-point interface
applications.
