AD8123 is a triple differential receiver with adjustable line equalization from Analog Devices. It can be used for keyboard-video-mouse (KVM), digital signage, RGB video over UTP cables and professional audio applications.
The AD8123 is a high‑speed triple differential receiver with adjustable line equalization. It compensates cable losses for UTP and coaxial cables up to 300 m, offering up to 55 dB peak gain at 100 MHz and fast 4.9 ns rise/fall times for 150 m of Cat‑5 cable. The device includes three cable‑compensation pins and an output‑offset adjust pin, allowing optimization for either UTP or coaxial cable.
The part is supplied in a 6 mm × 6 mm 40‑lead LFCSP package and operates from a +4.5 V to +5.5 V supply. Key specifications include a peak gain of 55 dB, a maximum differential output swing of 4 V p‑p, and an operating temperature range of –40 °C to +85 °C.
