According to the ADV7625 HW Manual, inputs pins for digital audio and digital video (pixel port and sync inputs) should be connected to ground through a 4K7 ohm resistor when not being used. However, I noticed that the following pins are floating (shown as connected to test points) in the ADV7625 eval board:
To simplify routing (and to avoid some potential PCB routing issues), is it OK to float these pins (or connect them directly to ground)? Do these pins have internal pull resistors? I am assuming that whatever applies to these pins would also apply to the P0-P7 pixel port inputs (which I also don't use).
Thank you in advance for your reply.
