3 Description

The DS90LV048A device is a quad CMOS flowthrough

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 highpower

PECL/ECL devices for high-speed point-topoint

interface applications.
