DESCRIPTION
Clip and TRS correction control. When HIGH, the TRS Blanking, ITU-R-601 clipping and TRS
insertion features are enabled.
TRS error indication. When HIGH, indicates a TRS error in the data stream such as a missing
TRS, an improperly placed TRS, or an incorrect TRS ID word.

ANC_DATA
O
Ancillary data indication. When HIGH, indicates that an ANC packet is coming out of the
device. The output is high from the beginning of the first header word to the end of the
checksum word of the ANC packet.
Power supply connection for the serial processing circuitry (nominally +5V).
Ground connection for the serial processing circuitry.
Power supply connection for the serial data outputs. To save power when not using the SDO/
SDO outputs, set this pin to ground.
Ground connection for the serial data outputs.
Power supply connection for the internal 75 ohm pullup resistor (nominally +5V) on the serial
data input lines.
Power supply connection for the internal 75 ohm pullup resistor (nominally +5V) on the serial
clock input lines.
Power supply connection for the parallel processing circuitry (nominally +5V).
Ground for the parallel processing circuitry.
