I Used for detection of S2-compatible DC that is superimposed to C signal.
I 4:3 image signal is selected when voltage less than 1.3V, 4:3 letterbox signal when
I 1.3V or more 2.5V or less, and 16:9 squeeze signal when voltage less than 2.5V. 4:3
I image signal is selected when the pins are open because they are pulled down to
GND via 100kΩ.
I Used for selection between composite video signal and S signal.
I Detection result is written to the status register. S signal is selected when voltage more
I than 3.5V, and composite video signal when voltage less than 3.5V. Composite video
I signal is selected when the pins are open because they are pulled down to 5V via
100kΩ.
I Used for selection of slave address for I2C bus.
90H is selected when voltage less than 1.5V, and 92H when more than 2.5V.
90H is selected when the pin are open.
I I2C bus signal input
I I2C bus signal input
O Used for output of S2-compatible DC that is superimposed to COUT3.
DC superimposition is done by connecting to COUT3 via capacitor. The pin is
controlled via I2C bus.
Connection of 4.7kΩ external resistor provides output impedance of 10±3kΩ that
conforms to S2.
I Connected to trap circuit for sub carrier.
I
I Mute for audio signal output.
Mute is on when voltage less than 1.3V and off when voltage more than 2.5V.
Mute is off when the pin is open.
I Internal reference bias input.
Connected to GND via capacitor.
