Hi AqidAyman,

I'm not sure I understand exactly what you mean by "they". Note that the expression "dedicated PLL input", used in Altera documentation, is a bit misleading. It is not exactly dedicated in the sense that it can be only used for driving a PLL. It can also be used as a normal input, even at the same time that it is used as the PLL clock input.

Wouldn't be possible to get an authoritative answer to this?

Thanks,
