In ADV7513, the pins going to the digital portion of the clock PLL (called PVDD in ADV7511) are connected to the pins going to the analog portion of the clock PLL (called PLVDD in ADV7511) and are called PVDD. I see we need to remove references to PLVDD in the ADV7513 documentation.
I'll have to discuss your second question with the ADV7513 experts.
