ADV7390 CLKIN Frequency

Hi, Support Team

I have a question about CLKIN frequency of ADV7390.

If 84MHz Clock input to CLKIN, what happens to ADV7390?
I know that the absolute maximum ratings of CLKIN is 80MHz, but I want to know actual ability of ADV7390.
Could you please let me know it in each case of RESET active and RESET non-active?

For example, if RESET is non-active, because it does not accept the clock as the device, 84MHz is OK?
In that case, what kind of data is output? (Unknown data? No output? etc.)

Best regards, TomY
