Product Summary
The MAX7452ESA+ is a complete front-end video-signal conditioner. It is designed to improve the quality of standard-definition video signals. The MAX7452ESA+ restores the DC level of the video input, correct for amplitude errors up to ±6dB, detect fault conditions, and filter out-of-band noise. The MAX7452ESA+ optimizes the signal quality for further video processing through a crosspoint switch or video decoder (ADC). Each device integrates an input video clamp, automatic gain control (AGC), loss-of-sync (LOS) detector, and an out-of-band noise/lowpass filter. The applications of the MAX7452ESA+ include Signal Conditioner for Standard-Definition, Video Inputs, Security Video Systems, Video-Switching Systems.
