I2C BUS Control 5-Input 2-Output AV Switch MM1495X
I2C BUS Control 5-Input 2-Output AV Switch
Monolithic IC MM1495X
Outline
This IC is a 5-input, 2-output AV switch with I2C BUS control, developed for use in TV. This IC supports S2
and Cenelec standards.
Features
1. Serial control by I2C BUS.
2. 5 - inputs, 2 - outputs (2 of the 5 input lines can be used for either composite or Y)
3. Built-in sync separation circuit
4. Built-in Y/C mix circuit
5. Video and audio switches can be controlled independently.
6. 6dB amp built in to video and audio systems.
7. Output voltage gain can be varied by mounting an external resistor on the audio input pin.
8. Slave address can be changed: 90H or 92H
9. Built-in 3-value identification function
Package
SOP-44A (MM1495XF)
SDIP-42A (MM1495XD)
Applications
1. TV
2. Other video equipment

I2C BUS is inter bus system controled by 2 lines (SDA, SCL).
Data are transmitted and received in the units of byte and Acknowledge.
It is transmitted by MSB first from the Start conditions.
[Control registers]
Control registers are data sent from the master for determining the switch conditions.
The data format is set as shown in the following figure.

Out of the Address byte, first 7bit are assigned to the slave address, while the residual 1bit is assigned to the
R/W bit.
Set the R/W bit to 0 when data are used control registers.
As MM1495 slave address, either 90H or 92H can be selected according to the ADR
terminal conditions. When ADR terminal is L, 90H is selected.
The following figure indicates the control contents of control registers and switches.
Each bit of control registers is reset to 0, when power-on.
No.

Out of the Address byte, first 7bit are assigned to the slave address, while the residual 1bit is assigned to the
R/W bit.
Set the R/W bit to 1 when data are used status registers.
As MM1495 slave address, either 91H or 93H can be selected according to the ADR terminal conditions.
When ADR terminal is L, 91H is selected.
Set the confirmation acknowledgement after the end of status register to non-acknowledgement.
The following figure shows the correspondence of the output data of status registers.

(1) VOUT is set to 2.1V, while CIN is set to 4.2V.
Be careful since the capacitor polarity may differ according to the comb filter bias.
(2) The case that a Y element is left by the Comb-filter character is presumed the condenser of CIN1, CIN2, and
there is it as 10µF.
You can use 0.01µF when a Y element isn't left in the croma output of Comb-filter.
