  • Product Details

    The MAX7452 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains the MAX7452. The MAX7452 is a low-cost, high-performance, complete front-end video-signal conditioner with automatic gain control (AGC) and a useradjustable back-porch clamp. The device includes an out-of-band noise filter, back-porch clamp, loss-of-sync (LOS) detector, ±6dB of AGC, and an output buffer capable of driving either a 150Ω video load or a highimpedance load. These features optimize the video signal quality for further video processing through a crosspoint device or video decoder. The EV kit operates from a single +5V power supply.
