Honored ContributorPLL? Cyclone ii? I/o
Is it possible to use the Cyclone ii PLL to divide down a 37.5Mhz clock on a standard input/output pin. Does it need to be on a dedicated Pin?

Honored ContributorOk thanks. So it looks like i may not be able to do this since my clock is going to a general I/O.
What stand-alone internal clock options does the cyclone ii have? Can it run completly independent without a crystal etc? How fast?
