M52791SP/FP
AV SWITCH with I2C BUS CONTROL
AUG.'98
PRELIMINARY
Notice. This is not a final specification.
Some parametric limits are subject to change.
6
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 .
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
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 .
I C BUS
I C 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 .
