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 designed 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) differential input signals and translates them
to 3V CMOS output levels. The receiver supports a
TRI-STATE function that 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
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 receivers. 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.
