Figure 10 Recommended Oscillator Circuits
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.
