ANALOG DEVICES AD8322 English products handbook AD8128 English products handbook
The AD8128 is a high‑speed differential receiver/equalizer designed to compensate for the transmission losses of unshielded twisted‑pair (UTP) CAT‑5 cables up to 100 m. It provides adjustable line equalization, broadband gain, and DC offset control for applications such as KVM, RGB video over UTP, professional video distribution, and security video.
The datasheet includes functional block diagrams, pin descriptions, typical performance curves, absolute maximum ratings, thermal resistance data, layout guidelines, and an ordering guide for the 8‑lead 3 mm × 3 mm LFCSP package. It also describes cascaded configurations for extending equalization to 200 m and lists available evaluation boards.
