製品概要

The AD8122 is a high-speed, triple differential receiver and equalizer designed to compensate for signal loss in UTP cables (up to 300m) and coaxial cables (up to 200m) by adjusting gain stages to counteract cable frequency response. It features high impedance differential inputs with excellent common-mode rejection for direct cable interfacing, and provides control inputs for cable compensation, filter adjustment, cable type selection, and DC output offset. The device also offers selectable gain (1 or 2) and is available in a 40-lead LFCSP, operating in a temperature range of −40°C to +85°C.
