I/O
I
Input the horizontal synchronizing signal.
I
It's polarity corresponds to both positive and negative.
I
Input from this pin does not be synchronized internally.
I
Input the horizontal vertical signal.
I
It's polarity corresponds to both positive and negative.
I
Input from this pin does not be synchronized internally.
—
The GND pin for analog circuit block.
—
Connect the filter for horizontal AFC. The frequency of the horizontal output is varied
by the volyage at this pin.
—
Connect the ceramic oscillator for horizontal oscillator.
—
The VCC pin. (9.0V)
O
DAC1 output pin. When TEST mode, VD or vertical sync signal to frequency counter
circuit is output.
O
DAC2 output pin. When TEST mode, HD or composite sync signal to frequency
counter circuit is output.
O
DAC3 output pin. This pin is open-collector system. When TEST mode, test pilses for
the shipping is output.
O
Clamp pulse output pin. CP mode at synchronization circuit is output.
O
HD output pin. This pin is open-collector system.
O
HD1/HD2 does not be synchronizing and they are output from this pin.
It's polarity is switched by BUS write function.
—
The GND pin for logic circuit block.
I/O
The SDA pin for I"C BUS.
I
The SCL pin for I"C BUS.
I
Slave address switch.
I
Input a signal to separate sync signal.
I
O
VD output pin. This pin is open-collector system.
O
VD1/VD2 does not be synchronizing and they are output from this pin.
It's polarity is switched by BUS write function.
