> Very good and practical articles, thanks a lot.

Yes, there's a lot of helpful information there. More than enough
for the average designer to make a good reliable oscillator, and
it doesn't hurt to have all the technical background

I tend to start with 22pF (for everything but 32kHz) as this
gets most crystals going. Then look at the waveform to check
there's no over-driving and also the frequency and adjust as
and if necessary. For applications that are more time-sensitive,
add a trimmer to get the frequency spot on
