MITSUMI Video Switch for DVD Recorders MM1697BJ
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.
Features
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. Includes 2 channels for detecting S-terminal connection

Switch Control Table
Note: When a Sdet terminal is not used, all mode can be controlled with only a CTRL terminal by making it
Sdet1 and 2= H (VCC).
When a Sdet terminal is used, please attach the pull-up resistor of 20kΩto Sdet1, Sdet2 terminal (3pin,
5pin).
