Perfect! Thank you. Regards, Carlos
For the DaVinci DVEVM, you can use a pin on the DC4 connector to isolate the on-board TVP5146 device from the VPFE interface. I would suggest using a pullup resistor on your daughter card for pin 2 of DC4 (CAPTURE_EN).However, the pullup resistor should NOT be connected to 3.3V. The control inputs of the SN74AVCB164245 are referenced to VCCB (the B side of the Dual Supply Bus Transceiver) which on this board is 1.8V. The B side connects to the DM644X device. Therefore the pullup resistor should be connected to 1.8V, which is available on DC4 on pins 41 and 42.
