3 Description
The DS90LV048A device 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) using
Low Voltage Differential Signaling (LVDS)
technology.
The DS90LV048A accepts low voltage (350 mV
typical) differential input signals and translates them
to 3-V 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 (100-Ω) input fail-safe. The receiver
output is 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 (for example,
DS90LV047A) provide a new alternative to high-
power PECL/ECL devices for high-speed point-to-
point interface applications.
