Note: C1, C2 = 30pF ± 10pF for crystals
For ceramic resonators, contact resonator manufacturer
Oscillation circuit is designed to be used either with a ceramic resonator or crystal oscillator. Since each crystal and ceramic resonator
have their own characteristics, the user should consult the crystal manufacturer for appropriate values of external components.
