Function
Outputs the SCP (Sand Castle Pulse).
The output signals are clamp pulse, horizontal blanking pulse, and
vertical blanking.
Logic block GND pin.
Input pin for the CP/HP pulse for operating the SW circuit.
CP is used as the clamp pulse and HP as the blanking pulse.
VCC pin for sync processing block and SW block.
Connected to 9V (standard).
Outputs Y/B-Y/R-Y or R/G/B.
Switches the YUV/RGB output by bus setting,
Pin for switching the slave address.
GND - 24H,
VCC - 2CH
GND pin for switch block.
Input pin for Y2/B-Y2/R-Y2 (YUV2 input) or R2/G2/B2.
I 2 C block GND pin.
Input pin for Y1/B-Y1/R-Y1 (YUV1 input) or R1/G1/B1.
High speed SW for switching the input of pins 25, 26, 27 (YUV2)
and 29, 30, 31 (YUV1).
Threshold is 0.7V.
SCL pin for I
2
C bus.
SDA pin for I
2
C bus.
DAC monitor pin for IC shipping test.
GND pin.
Outputs the Y signal passing through the fsc TRAP (can be turned
ON/OFF by BUS) and Y delay line circuit.
1 bit DAC output pin.
