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).

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
