I
Used for detection of S2-compatible DC that is superimposed to C signal.
I
4:3 image signal is selected when voltage ? 1.3V, 4:3 letterbox signal when 1.3V
I
< voltage ? 2.5V, and 16:9 squeeze signal when voltage > 2.5V. 4:3 image signal is
I
selected when the pins are open because they are pulled down to GND via 100K?.
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 ?
I
3.5V, and composite video signal when voltage > 3.5V. Composite video signal is
I
selected when the pins are open because they are pulled down to 5V via 100K?.
I
Used for selection of slave address for 12C bus.
90H is selected when voltage ? 1.5V, and 92H when ? 2.5V.
90H is selected when the pin are open.
I
12C bus signal input
I
12C 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 12C bus.
Connection of 4.7k? external resistor provides output impedance of 10?3K? that
conforms to S2.
I
Connected to trap circuit for sub carrier.
I
I
Mute for audio signal output.
Mute is on when voltage ? 1.3V and off when voltage ? 2.5V.
Mute is off when the pin is open.
I
Internal reference bias input.
Connected to GND via capacitor.
