DS90C032
LVDS Quad CMOS Differential Line Receiver
General Description
The DS90C032 is a quad CMOS differential line receiver de-
signed for applications requiring ultra low power dissipation
and high data rates. The device is designed to support data
rates in excess of 155.5 Mbps (77.7 MHz) utilizing Low Volt-
age Differential Signaling (LVDS) technology.
The DS90C032 accepts low voltage (350 mV) differential in-
put signals and translates them to CMOS (TTL compatible)
output levels. The receiver supports a TRI-STATE® function
that may be used to multiplex outputs. The receiver also sup-
ports OPEN, shorted and terminated (100Ω) input Fail-safe.
Receiver output will be HIGH for all fail-safe conditions.
The DS90C032 and companion line driver (DS90C031) pro-
vide a new alternative to high power psuedo-ECL devices for
high speed point-to-point interface applications.
