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 did get a DE-2 board and it was very helpful.

Ok, great. These are nice boards, with lots of peripherals. You will also be able to get lots of example code.

So far Ive made 2 successful circuits that work great. I use Verilog exclusivley.

Once you have got some basic circuits working, you'll want to create components with 'standardized' control interfaces. In the Altera-world, these components adhere to the Avalon bus specification. In some cases you can use Altera-supplied IP, while in others you will need to develop your own. Part of the development process involves simulation of the components using the Avalon Verification IP suite; its written in SystemVerilog.

Take a look at the Altera documentation for these, and ask questions when you need help. There are a couple of good Altera webinars on these topics.
