I did ask Sparkfun for the datasheet ... waiting on a response to that.
I intend to accurately time some pulses from various sources, and from past experience (PIC stuff), I know that resonators have not been able to handle the precision I need. I will admit though, that I've been using a Murata resonator lately that works decently with 0.2% error. Let's see what Sparkfun says that they're using, and I'll be able to better determine what alternatives will fit.
