MITSUMI I2C BUS Control 5-Input 2-Output AV Switch MM1313 I2C BUS Control 5-Input 2-Output AV Switch Monolithic IC MM1313 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. Package SDIP-42A (MM1313AD, MM1313BD) Applications 1. Televisions 2.
