If you have a look in the "assembly" folder, just next to the one with the schematics, and look for an Excel file with "BOM" in the name. It is the list of all the components, with the manufacturer names and part numbers.

These are standard 3.3V crystal oscillators, available from many vendors in various package styles. You'll find them at any catalog distributor of your choice.

I clearly said crystal oscillator in contrast to just a crystal. You would have to design a crystal oscillator around the crystal, e.g. by utilizing an unbuffered inverter. But it's only simple for low frequencies, I strongly suggest to use a ready-made oscillator. Cylone III PLL gives you the option to use nearly any clock input frequency you can realize.
