Video signal input.
Composite video signal input
Y/C-separated signal input terminal for luminance signal input.
YIN1 to feed in the Y/C-separated signal of VOUT1 output.
Y/C-separated signal input terminal for chrominance signal input.
CIN1 to feed in the Y/C-separated signal of VOUT1 output.
Audio signal input terminal.
Video signal output terminal for composite video signal output.
Video signal output terminal for selection between composite video signal output and
luminance signal output by I2C Bus control.
Video signal output terminal for luminance signal output.
Video signal output terminal for chrominance signal output.
Audio signal output terminal.
Used to detect C signal-superimposed, S2-compatible DC level. 4:3 video signal when
below 1.3V. 4:3 letterbox signal when between 1.3V and 2.5V. 16:9 image squeeze
signal when above 2.5V. To be pulled down to GDN at 100K
 to produce 4:3 video
signal when open.
Used to switch between composite video and S signals. Detection results to be written
in status register. S signal when below 3.5V. Composite video signal when above 3.5V.
To be pulled up to 5V at 100K
 to produce composite video signal when open.
Used to select I2C Bus slave address. 90H when below 1.5V. 92H when above 2.5V.
90H also when the terminal is open.
I2C Bus signal input terminal.
I2C Bus signal input terminal.
Used to feed out S2-compatible DC level to be superimposed on COUT3 output. DC to
be superimposed by connecting to COUT3 output via a capacitor. Control to be made
by I2C Bus. S2-specified output impedance of 10 ±3K
 to be realized by adding an
external resistance of 4.7K
.
Subcarrier trap circuit to be connected.
Audio signal output mute terminal. Mute off when below 1.3V. Mute on when above
2.5V. Mute off when the terminal is open.
Internal reference bias (Vcc/2) terminal. To be connected to GND with a capacitor in
between.
