78 CLIP_TRS I Clip and TRS correction control. When HIGH, the TRS Blanking, ITU-R-601 clippi ng and TRS
insertion features are enabled.
79 TRS_ERR 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.
80 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 begi nning of the first header word to the end of the
check sum word of the ANC pack et.
1, 4, 13 VDD Power supp ly connect ion for the serial processing circuitry (nom5V).
2, 3, 14 GND Ground conne ction for the serial processing circuitry.
69 SVDD Power supp ly connect ion for the serial data outputs. To save power when not using the SDO/
SDO outputs, set this pin to ground.
72 SGND Ground conne ction for the serial data outputs.
5, 8 VDD_SDI, SDI Power supp ly connect ion for the internal 75 ohm pullup resistor (nom5V) on the serial
data input lines.
9, 12 VDD_SCI, SCI Power supp ly connect ion for the internal 75 ohm pullup resistor (nom5V) on the serial
clock input lines.
29,51,68 VDD Power supp ly connect ion for the parallel processing circuitry (nom5V).
30,50,67 GND Ground for the parallel processing circuitry.
