Qualified for automotive applications APPLICATIONS Backplane data transmission Cable data transmission Clock distribution GENERAL DESCRIPTION The ADN4667 is a quad, CMOS, low voltage differential signaling The ADN4667 also offers active high and active low enable/ (LVDS) line driver offering data rates of over 400 Mbps (200 MHz) disable inputs (EN and EN ). These inputs control all four drivers and ultralow power consumption. It features a flow through and turn off the current outputs in the disabled state to reduce pinout for easy PCB layout and separation of input and output the quiescent power consumption to typically 10 mW. signals. The ADN4667 and its companion LVDS receiver, the ADN4668, The device accepts low voltage TTL/CMOS logic signals and offer a new solution to high speed, point-to-point data trans- converts them to a differential current output of typically 3.1 mA mission, and a low power alternative to emitter-coupled logic for driving a transmission medium such as a twisted pair cable. (ECL) or positive emitter-coupled logic (PECL). The transmitted signal develops a differential voltage of typi- cally 310 mV across a termination resistor at the receiving end. This is converted back to a TTL/CMOS logic level by an LVDS receiver, such as the ADN4668. Rev. B Information furnished by Analog Devices is believed to be accurate and reliable.
