Hi,

In that link, PLL Input clock frequency mentioned as 5MHz to 472.5MHz. So we need to select the external crystal oscillator to be selected in that range, since we cannot drive PLL with internal oscillator. Whether my understanding is correct or not?

I have attached the snapshot from MAX10 handbook for reference.
