MM1492

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 I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF Block Diagram 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 2 3 4 5 6 7 8 9 10 11 V1-V V1-L V1-Y V1-R V1-C S1 V2-V V2-L V2-Y V2-R V2-C 12 13 14 15 16 17 18 19 20 21 22 S2 V3-V V3-L V3-R STV-V STV-L STV-R YIN2 ADR CIN2 GND 23 24 25 26 27 28 29 30 31 32 33 VOUT2 ROUT2 COUT2 LOUT2 YOUT2 GND SDA SCL MUTE CIN1 GND 34 35 36 37 38 39 40 41 42 43 44 YIN1 ROUT1 LOUT1 VOUT1 BIAS YOUT1 VCC COUT1 MTV-R MTV-V MTV-L Pin Description Pin No. Pin name 1 3 7 9 13 16 19 34 43 2 4 8 10 14 15 17 18 42 44 V1-V V1-Y V2-V V2-Y V3-V STV-V YIN2 YIN1 MTV-V V1-L V1-R V2-L V2-R V3-L V3-R STV-L STV-R MTV-R MTV-L Audio input terminal Functions Video input terminal (Composite or Y) Internal equivalet circuit diagram *Sync chip clamp MITSUMI I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF Pin No. Pin name 5 11 21 32 V1-C V2-C CIN2 CIN1 (Croma) Functions Video input terminal Internal equivalet circuit diagram 6 12 S1 S2 Distinction 3-effects input terminal DC Detect 20 31 ADR Mute Sleve address select Audio Mute terminal 22 28 33 23 37 GND GND VOUT2 VOUT1 Composite video out 24 26 35 36 ROUT2 LOUT2 ROUT1 LOUT1 Audio out terminal 25 27 39 41 COUT2 YOUT2 YOUT1 COUT1 S -Video out terminal MITSUMI I2C BUS Controlled 5-Input 2-Output AV Switch MM1492AF Pin No. Pin name 29 SDA Functions Data input from I C 2 Internal equivalet circuit diagram 30 SCL CLK input from I2C 38 BIAS Internal bias terminal 40 VCC VCC Absolute Maximum Ratings Item Storage temperature Operating temperature Power supply voltage Allowable loss (Ta=25°C) Symbol TSTG TOPR VCCmax.
