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?

I hope I dont seem too timid in my posts, but being a beginner Altera user I feel better knowing that I am not overlooking something obvious.

Trust me, with thousands of pages of handbooks, data sheets, user guides, megacore functions, etc, there is nothing obvious! But the tools are pretty simple to use, so make use of them.

Since you are a beginner, my words of advice are to get yourself a decent evaluation board, eg., one of the Terasic DE-series boards, and design a couple of simple designs from scratch, eg., blink LEDs. Then learn how to use the Modelsim simulator to simulate your designs.

What are you using for a hardware description language? VHDL, Verilog, or SystemVerilog? I use VHDL extensively, however, I'm starting to use SystemVerilog, since a lot of the newer Altera IP is being delivered in that form (eg., the Avalon Verification IP suite).

Cheers,

Dave
