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.
