PC board equalizer — what it does in the signal chain
The Maxim Integrated MAX3785UTT-T is a PC board equalizer, a signal-conditioning IC used to compensate for frequency-dependent losses on PCB traces or cables. It sits between the transmission line and the receiver, restoring signal integrity by boosting high-frequency content that gets attenuated over distance. Typical applications include backplane routing, high-speed serial links, and any channel where trace length or dielectric losses degrade the eye diagram.
