GENERAL DESCRIPTION

The ADN4661 is a single, CMOS, low voltage differential

signaling (LVDS) line driver offering data rates of over

600 Mbps (300 MHz) and ultra-low power consumption.

It features a flow-through pinout for easy PCB layout and

separation of input and output signals.

The device accepts low voltage TTL/CMOS logic signals and

converts them to a differential current output of typically

±3.1 mA for driving a transmission medium such as a twisted-

pair cable. The transmitted signal develops a differential voltage

of typically ±355 mV across a termination resistor at the receiv-

ing end, and this is converted back to a TTL/CMOS logic level

by a line receiver.

The ADN4661 and a companion LVDS receiver offer a new

solution to high speed point-to-point data transmission, and a

low power alternative to emitter-coupled logic (ECL) or positive

emitter-coupled logic (PECL).
