M52790SP/FP
AV SWITCH with I2C BUS CONTROL
DESCRIPTION
The M52790 is AV switch semiconductor integrated circuit with
I2C bus control .
This IC contains 2-channels of 4-input audio switches and 2-
channels of 4-input video switches. Each channel can be
controled independently .
The video switches contain amplifiers can be controled a gain of
output 0dB or 6dB .
FEATURES
•Video and stereo sound switches in one package
•Wide frequency range ( video switch )...........DC~20MHz
•High separation ( video switch )
.................Crosstalk -60dB ( typ. ) at 1MHz
•Two types of packages are provided : SDIP with a lead pitch of
1.778mm ( M52790SP ) ; and SSOP with a lead pitch of 0.8mm
( M52790FP ) .

M52790SP/FP
AV SWITCH with I2C BUS CONTROL
I2 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
P
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 ) . SW1 is controled by
DATA1 ,SW2 is controled by DATA2 .
