Video Switch for DVD Recorders MM1697BJ MITSUMI Video Switch for DVD Recorders Monolithic IC MM1697BJ Outline This IC is a video switch IC that includes an LPF (anti-aliasing filter) required before A/D conversion for DVD recorders, etc. It provides three input channels for composite video (CV), three input channels for S-Video (Y, C), one output channel for Y/CVOUT (used for both Y and CV), one output channel for COUT, and one output channel for CVOUT (select VIN or YIN+CIN). It also includes S-terminal connection detection function, which is ideal as a video input switch for DVD recorders that perform A/D conversion. du c ut Pr o 1. Input channel: Composite video input *** 3 channels S-Video (Y, C) *** 3 channels 2. Includes a high performance LPF (anti-aliasing filter) -3dB pass bandwidth: 7MHz (typ.) Attenuation at 10.7MHz: -36dB (typ.) Attenuation at 13.5MHz: -40dB (typ.) Attenuation at 27.0MHz: -37dB (typ.) 3. Includes a Y+C amplifier (Y/C MIX) 4.
