MITSUMI I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF I2C BUS Controlled 5-Input 2-Output AV Switch Monolithic IC MM1492AF Outline This IC is a 5-input 2-output AV switch controlled by the I2C BUS developed for use in television. Because there are 2 outputs, it supports 2 screens and P-IN-P, and also supports an external output (monitor) pin. Features (1) Serial control by I2C BUS (2) 5 inputs, 2 outputs (3) 1 Y/C (S pin) inputs, 2 outputs (4) The video and audio switches can be controlled independently (5) Built-in 6dB amp for video (6) Built-in Y/C (S pin) mix circuit (7) One of the two audio outputs has a built-in -6dB ON/OFF switch (8) Slave address can be changed. 90H and 92H possible. (9) Audio muting from external pin possible (10) Maintains high impedance even when I2C BUS line (SDA, SCL) power supply is off. (11) Built-in 3 value discrimination function built-in (12) Built-in power ON reset function (13) Supports 2 screens and P-IN-P. Also supports external output (monitor) pin. Package SOP-44B Applications (1) TV (2) Other video equipment MITSUMI Block Diagram I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF MITSUMI I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF Pin Assignment 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 SOP-44B 1 V1-V 12 S2 23 VOUT2 34 YIN1 2 V1-L 13 V3-V 24 ROUT2 35 ROUT1 3 V1-Y 14 V3-L 25 COUT2 36 LOUT1 4 V1-R 15 V3-R 26 LOUT2 ...
