I Used to detect C signal-superimposed, S2-compatible DC level. 4:3 video signal when
I below 1.3V. 4:3 letterbox signal when between 1.3V and 2.5V. 16:9 image squeeze
I signal when above 2.5V. To be pulled down to GDN at 100KΩ to produce 4:3 video
I signal when open.
I Used to switch between composite video and S signals. Detection results to be written
I in status register. S signal when below 3.5V. Composite video signal when above 3.5V.
I To be pulled up to 5V at 100KΩ to produce composite video signal when open.

I Used to select I2C Bus slave address. 90H when below 1.5V. 92H when above 2.5V.
90H also when the terminal is open.
I I2C Bus signal input terminal.
I I2C Bus signal input terminal.
O 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 ±3KΩ to be realized by adding an
external resistance of 4.7KΩ.
I Subcarrier trap circuit to be connected.
I
I Audio signal output mute terminal. Mute off when below 1.3V. Mute on when above
2.5V. Mute off when the terminal is open.
I Internal reference bias (Vcc/2) terminal. To be connected to GND with a capacitor in
between.
