I've got a 32.768 kHz crystal running on a microprocessor and I'm concerned about the glitches I'm seeing on the waveform, should I be? The loading cap spec for the crystal is 12.5 pF (it's a CM8V from Golledge). I've loaded the crystal with 20 pF caps (tried to account for stray capacitances). I've attached a photo from my oscilloscope. My concern is, that if the crystal is fed into a schmitt trigger in the micro (silicon labs gecko), the glitches might cause frequency issues. Does this look normal, any tips?
