How can I calculate the right capacitance for my µC (MCS08AW16)?
Is it C1 and C2 = 10pF?
I would use the following crystal:
HC-49SM (Hosonic-Electronic):
Shunt capacitance: max. 7pF
load capacitance: min: 10pF
drive level: typ. 100µW => max. 500µW
Rf: 1MOhm
Rs: 0 Ohm
C1: ??
C2: ??
Thank you very much!
