AV SWITCH with I2C BUS CONTROL

I C BUS
I 2C BUS(Inter IC BUS)is multi master bus system developed by PHILIPS . Two wires ( SDA - serial data,
SCL - serial clock ) realize functions of start , stop , transferring data , synchronization and arbitration. The
output stages of device connected to the bus must have an open drain or open collector in order to perform the
wired-AND function .

S ; Start condition, a high to low transition of the SDA line while SCL is high
P ; Stop condition, a low to high transition of the SDA line while SCL is high
A ; Acknownledge
Every byte put on the SDA line must be 8-bits long . Each byte has to be followed by an acknowledge bit. Data
is transferred with the most significant bit (MSB ) first . The data on the SDA line must be stable during the
HIGH period of the clock . The HIGH or LOW state of the data line can only change when the clock signal on
the SCL line is LOW .
CONTROL
This IC controls 2-channel switchs with 2-byte data ( DATA1 and DATA2 ) . Video switches are
controled by DATA1 , audio switches are controled by DATA2 .

Note how to use this IC
Input signal with sufficient low impedance to input terminal.
The capacitance of output terminal as small as possible.
Set the capacitance between Vcc and GND near the pins if possible.
Assign an area as large as possible for grounding.
Power-on Reset
The M52791 has an intermal power-on reset function that sets each
control r egister to "0" during IC power ON.
The power-on reset VTH has 2.5V.
