GENERAL DESCRIPTION

The ADN4665 is a quad-channel, CMOS, low voltage differential

signaling (LVDS) line driver offering data rates of over 400 Mbps

(200 MHz) and ultralow power consumption.

The device accepts low voltage TTL/CMOS logic signals and

converts them to a differential current output of typically ±3.5 mA

for driving a transmission medium such as a twisted pair cable.

The transmitted signal develops a differential voltage of typi-

cally ±350 mV across a termination resistor at the receiving end.

This voltage is converted back to a TTL/CMOS logic level by an

LVDS receiver.

The ADN4665 also offers active high and active low enable/

disable inputs (EN and EN). These inputs control all four drivers

and turn off the current outputs in the disabled state to reduce

the quiescent power consumption to typically 10 mW.

The ADN4665 offers a new solution to high speed, point-to-point

data transmission and offers a low power alternative to emitter-

coupled logic (ECL) or positive emitter-coupled logic (PECL).
