TYPE
I Clip and TRS correction control. When HIGH, the TRS Blanking, ITU-R-601 clipping and TRS
insertion features are enabled.
O TRS error i ndication. 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.
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
check sum word of the ANC pack et.
Power supply connect ion for the serial processing circuitry (nominally +5V).
Ground conne ction for the serial processing circuitry.
Power supply connect ion for the serial data outputs. To save power when not using the SDO/
SDO outputs, set this pin to ground.
Ground conne ction for the serial data outputs.
Power supply connect ion for the internal 75 ohm pullup resistor (nominally +5V) on the serial
data input lines.
Power supply connect ion for the internal 75 ohm pullup resistor (nominally +5V) on the serial
clock input lines.
Power supply connect ion for the parallel processing circuitry (nominally +5V).
Ground for the parallel processing circuitry.
