The AD8122 is a high‑speed three‑channel differential receiver/equalizer with up to 300 m UTP or 200 m coax cable compensation.
The AD8122 from Analog Devices provides high‑speed three‑channel differential reception and equalization for video and KVM applications. It offers adjustable control voltages for high‑frequency peak (VPEAK), broadband flat gain (VGAIN), low‑pass filter cutoff (VFILTER) and DC offset (VOFFSET), allowing compensation of long cable runs.
The device is supplied in a 40‑pin 6 mm × 6 mm LFCSP package and operates over a wide temperature range (‑40 °C to +85 °C). Its specifications include up to 300 m UTP or 200 m coaxial cable compensation, 60 MHz–120 MHz bandwidth depending on cable length, and low output offset voltages. This manual is written in Chinese.
