The AD8143 is a high-speed, triple differential receiver with comparators. It features high speed bandwidth, high common mode rejection ratio, wide input impedance, adjustable gain, etc.
The AD8143 is a high‑speed, triple differential‑to‑single‑ended receiver designed for RGB video and other high‑speed data over unshielded twisted‑pair cables. It includes two on‑chip comparators for digital or sync signals and can be paired with AD8133/AD8134 drivers for complete RGB‑over‑UTP solutions.
Key features include a 160 MHz 3‑dB bandwidth, 1000 V/µs slew rate, 8 ns 1 % settling time, 65 dB CMRR at 10 MHz, and a wide supply range of +5 V to +12 V. The device is offered in a 32‑lead LFCSP package and operates from –40 °C to +85 °C.
