For ceramic resonators, contact re so nator 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 appropria te values of external components.
