GENERAL DESCRIPTION
The ADN4663 is a dual, CMOS, low voltage differential
signaling (LVDS) line driver offering data rates of over
600 Mbps (300 MHz), and ultralow 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
receiving end, and this is converted back to a TTL/CMOS logic
level by a line receiver.
The ADN4663 and a companion 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).
