Hello,
I have a question regarding the accuracy of a 1Hz timebase generator circuit. I'm using a 32.768kHz crystal which the manufacturer specifies a load capacitance of 12.5pF....this circuit uses 33pF capacitors. That is rather far from 12, is it not? My question is would there be a noticeable drift in accuracy if I used the 33pF caps? Can I just substitute 12pF caps in their place?
Thanks much!
