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?

Yes I should prob just try it, however I think I may have issues. I originally stated my problem incorrectly. I am actually trying to multiply the 37.5Mhz coming from a DSP to like say 10x (375Mhz) in order to offload some intensive real-time math calculations from the DSP. I do not need an external clock just internal for the calculations.
