AV Switch for I²C BUS Control, 4-input, 3-output

and Canal Plus Compatible

Monolithic IC MM1422, 1423, 1442, 1443

Outline

These ICs are four-input, three-output AV switches under I²C BUS control with Canal Plus support, intended

for use in VCRs and DVD for the European market. There are four models, described below. Audio

subsystems are either stereo or monaural; video subsystems either do or do not have a clamping circuit.

Features

1. I²C BUS serial control.

2. Internal two-output 75Ωvideo driver, internal two-output 600Ω audio driver.

3. Audio mute function through an external pin.

4. Operating power supply voltage

11 to 13 V

5. Models both with and without video subsystem clamp.

6. Models with monaural and stereo audio subsystems.

I²C BUS (Inter IC BUS) is an inter bus system developed by Philips Co. It transmits and receives data through

2 (SDA, SCL) lines. Data are transmitted and received in the units of bytes by MSB first from the start

condition.

[Control registers]

Control registers are data sent from the master for determining the switch condition of the MM1422 series.

MITSUMI

The data format of the MM1422 series is set as shown in the above figure. Out of the address bytes, first 7

bits are assigned to the slave addresses, while the residual 1 bit is assigned to the R/W bit. Set the R/W bit to

0 when data are used as control registers. Slave address of the MM1422 series is 90H. Each bit of control

registers is reset to 0. MM1422 series consists of one address byte and two control data bytes(3 bytes in

total). For details of the control contents of control register 1 and 2, refer to the separate table.

All data over the limited length (4th and subsequent bytes) are fully neglected. Because of this, the faulty

operation that switch changes by the data after the 4th byte doesn't occur.

Each audio output can be set to mute by setting MUTE terminal to high.

[Status registers]

There is no preparation of the status register in MM1422 series. A status register returns all the 1 when is set

in the R/W bit.
