What criteria should one keep in mind when choosing oscillators for use with fpgas?

There are multiple properties that define behaviour of circuits that generate clock signals for use with digital circuits. What are the important things that must be considered when choosing oscilla...

Agree with the comment on the Si53xx series parts, especially if you need the flexibility in frequency and/or other clock frequencies. Able to lock to an external frequency source as well (useful for datacom applications). Requires a local crystal (like 25MHz) or reference clock source. Very low jitter on the outputs.

Of course the SiLabs solution will be pricier than just an oscillator at a given fixed frequency.
