Clock stability: Pocket Beagle

[Venkatesh Vadde]

This one is for Jason Kridner or anyone else in the know of clock specs on the Pocket Beagle. Do we know what the clock stability is in terms of +/-ppm of drift? Any data on the phase noise of the master clock? Knowing this would help us decide if we need an external TCXO or if we can use the crystal oscillator onboard.

Thanks,

Venky
