DS90LV048A
3V LVDS Quad CMOS Differential Line Receiver
General Description
The DS90LV048A is a quad CMOS flow-through differential
line receiver designed for applications requiring ultra low
power dissipation and high data rates. The device is de-
signed to support data rates in excess of 400 Mbps (200
MHz) utilizing Low Voltage Differential Signaling (LVDS)
technology.
The DS90LV048A accepts low voltage (350 mV typical) dif-
ferential input signals and translates them to 3V CMOS out-
put levels. The receiver supports a TRI-STATE® function that
may be used to multiplex outputs. The receiver also supports
open, shorted and terminated (100
Ω) input fail-safe. The re-
ceiver output will be HIGH for all fail-safe conditions. The
DS90LV048A has a flow-through pinout for easy PCB layout.
The EN and EN* inputs are ANDed together and control the
TRI-STATE outputs. The enables are common to all four re-
ceivers. The DS90LV048A and companion LVDS line driver
(eg. DS90LV047A) provide a new alternative to high power
PECL/ECL devices for high speed point-to-point interface
applications.
