Default SA602A oscillator load capacitance

I'm trying to figure out the load capacitance of the oscillator pins 6
and 7 on the SA602A.

...suggests...oscillator is about 8.5p.

All things considered in your case, I'd use the series coupling approach.

I like that idea, since the series capacitance reduces the effect of
unknowns on the oscillator side. Using my estimate above and given my
existing caps, I tried a 33p in series and got to 14.849995MHz, which
is a vast improvement.

Thanks!
