MAX7451 Overview
The MAX7450/MAX7451/MAX7452 plete front-end video-signal conditioners are designed to improve the quality of standard-definition video signals. The devices restore the DC level of the video input, correct for amplitude errors up to ±6dB, detect fault conditions, and filter out-of-band noise. The MAX7450/MAX7451/ MAX7452 optimize the signal quality for further video processing through a crosspoint switch or video...
