I2C BUS CONTROLLED VIDEO PRE-AMP FOR HIGH RESOLUTION COLOR DISPLAY
APPLICATION METHOD FOR M61311SP/M61316SP
ABOUT CLAMP PULSE INPUT
Clamp pulse needs to be always inputted.
Clamp pulse width is recommended :
15KHz at 1.0 uS over
30KHz at 0.5 uS over
64KHz at 0.3 uS over
The clamp pulse circuit in ordinary set is a long round about way,
and beside high voltage, sometimes connect to external terminal,
it is very easy affected by large surge.
Therfore, the fig. shown right is recommended.

NOTICE OF APPLICATION
Make the nearest distanse between output and pull down resister.
Recommend this resister is 1to 3 Kohm.
Power dissipation in 3Kohm is smaller than 1Kohm.
Recommend pedestal voltage of IC output signal is 2V.
As for the low level of the pulse input of OSD BLK, OSD, Clamp Pulse, Retrace BLK etc., avoid consisting
the GND level or under.
PIN31 connect to the voltage that stabilized, and pay attention as surge etc. does not flow into.
VCC(12V,5V) connects to the power supply that stabilized, and bypass-capacitor connects near the terminal.
When capacitor is connected to Pin29, it sometimes oscillates. Do not connect capacitor to Pin29.
Connect to bypass-capacitance of the DC line near the terminal.
Connect to the NC Pin to GND.
The time(t) is from fall of 9bit of SCL to rise of Acknowledge.
About the fowarding of IIC BUS, the time(t) changes with the resistance that connected outside.
The next SCL does not overlap into this time(t).
