C BUS Control 5-Input 2-Output AV Switch
Monolithic IC MM1495X
Outline
This IC is a 5-input, 2-output AV switch with I
2
C BUS control, developed for use in TV. This IC supports S2
and Cenelec standards.
Features
1. Serial control by I
2
C 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

C 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.
MM1495 consists of one address byte and three control data bytes (4bytes in total).
All data over the limited length (5th and subsequent bytes) are fully neglected.
For details of the control contents of switches, refer to the separate table.

[Status registers]
Status registers are data to inform the master of the device status.
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 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.
