#106395 - Burden caps appear to be in series
Responding to: ???'s previous message
Kevin said:
Finally, it seems your computation is based upon just one 18pf cap + 5pf (23pf) / 2 = 11.5 (12pf) Is that correct?

The two caps appear to be in series for the crystal. So, the capacitive load is (burden cap + XTAL port stray capacitance) / 2. Two identical caps in series give a capacitance of half the single capacitance.

I'll ask a million questions for a week, but hardly even one question after that. Once I get the first loader and then the first circuit built, the silence will be deafening!

Kevin, don't stop asking! The more the better! It's a plain pleasure to discuss with someone how is such eager to learn like you. Keep the shining in your eyes...
