What effect does selecting the wrong capacitance have? Does it skew the frequency, alter the shape of the waveform produced, or something entirely different? Is there an obvious correlation between too low and too high capacitance? Is it a case of slight errors, or orders of magnitude?
May not oscillate.
May work perfectly.
Factor of 2 in capacitance usually OK, but not always.
Depends on IC used, layout, how Murphy is feeling and phase of Moon.
Crystal oscillators approach more closely to analog and to black magic than sane people want to get on a good day. In many cases they "just work" and the arcanery is well hidden. You MAY find that capacitance that is off by a factor or 2 or even 5x still works OK. Or, you may not. When they don't work as hoped they can be most obdurate obstinate obnoxious odious and generally overwhelmingly annoying.
