Single, 3 V, CMOS, LVDS, High Speed Differential Driver

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).
