I/O
— Ground pin of the analog circuit section.
I An external low-pass filter is connected.
I The free-running frequency of VCO is determined.
I Oscillation input pin. This pin must be secured to the ground level.
O Oscillation output pin. (NC)
— Pin through which power is supplied to the analog circuit section.
I Pin through which the field judging signal is input. When the signal goes to "H", it becomes ODD.
I The horizontal synchronization signal is input. (Input polarity can be set.)

I Mask option function. When the serial three-wire is used, this terminal is usually fixed to "H".
I The vertical synchronization signal is input. (Input polarity can be set.)
I When set at "L", the inside of IC is initialized.
I Pin through which power is supplied to the digital circuit section.
Serial clock input terminal. When set at I
I
three-wire is used, this terminal functions as the serial clock input terminal.
Serial data input and output terminal. When set at I
I/O
the serial three-wire is used, this terminal functions as the serial data input terminal.
Chip select input terminal. When set at I
"H". When the serial three-wire is used and this terminal is level "L", the serial data and serial
I
clock are enabled. When the serial three-wire is used and this terminal is level "H", the serial
data and serial clock are disabled.
—
— Ground pin of the digital circuit section.
O This terminal can be set to output the dot clock.
O This terminal outputs the timing of blanking 2 in the form of positive logic.
O This terminal outputs the timing of blanking 1 in the form of positive logic.
I This terminal is the pin through which power is supplied to the DAC output port system.
O This terminal outputs the intensity signal.
O This terminal outputs the blue signal.
O This terminal outputs the green signal.
O This terminal outputs the red signal.
I This terminal is the ground pin of the DAC output port system.
Function
2 C, this terminal functions as SCL. When the serial
2 C, this terminal functions as SDA. When
2
C, this terminal is not used; it is fixed to either "L" or
