CAPC2, CAPY2, CAPY1, CML and REFOUT pins of ADV7181D.

Hello.

I have questions about CAPC2, CAPY2, CAPY1, CML and REFOUT pins of ADV7181D.

Question 1:
Could you tell me how much voltage can be seen as maximum at these pins?

Question 2:
How much withstand voltage of the capacitors should we use for these pins?
Do we have any problem when we use capacitors with withstand voltage of 6.3V or 10V?

Thank you!
Best regards.
