PLL? 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?

In that case you will need to feed the 37.5Mhz clock signal from the DSP to a dedicated clock input.

Running some logic at 375MHz inside the Cyclone II could be a bit tricky...
