Outline

This IC is a 5-input 2-output AV switch with I2C control, developed for use in televisions. Two outputs enable it to support two screens or picture-in-picture.

Features

1. Serial control by I2C bus.

2. 5-inputs, 2-outputs.

3. Video and audio system switches can be controlled independently.

4. 6dB amplifier built in to video system.

5. Built-in Y/C MIX circuit.

6. Slave address can be changed : 90H or 92H.

7. Audio muting possible by external pin.

8. Maintains high impedance even when I2C BUS line (SDA, SCL) power supply is off.

9. Built-in 3 value discrimination function.

10.On-chip power ON reset function.

11.Two types of audio input impedance : 60kΩ and 30kΩ.

MM1313AD : 60kΩ MM1313BD : 30kΩ

12.Supports 2-screen or P-IN-P TV.
