ADV7280 EPAD (EP) connection

I made the video decoder board, and I will start design verification.

Unfortunately I had mistaken that I forgot connect DGND pins (pin 1 and 4) to GND (digital ground) of board.

That is, DGND pins (pin 1 and 4) and GND are not connected.

I will fix this mistake in the future, but I want to continue design verification using this board.


Here is my questions.

1. Are AAA and BBB internally connected?
2. Is it possible to continue the evaluation as it is?

3. Should I connect DGND pins to GND before start evaluation?


Please advise as soon as possible.


Best regards,
