[Outline]
This is a video switch IC with I
2C bus control developed for high-resolution TVs, PDP and projection TVs. It can switch 4 color difference signal lines (component signals), 5 S-video signal lines and 8 composite signal lines.
Design of the input switch block can be simplified by using this IC with MM1631 (audio switch IC).
[Features]
1. |
Supports component signals (enables 4-input switching and 5-input S-video signal switching) frequency response: 50MHz |
2. |
Enables 8-input switching of component signals |
3. |
Serial control by I2C bus |
4. |
Includes a 0dB/6dB switching amp (OUT1/OUT2/OUT4) |
5. |
Includes a filter (13.5MHz LPF) (slew selection possible) |
6. |
Includes D-pin detection and S-pin detection functions |
7. |
The VOUT3, YOUT3, and COUT3 pins support 75Ω drive. |
