CLOCK AND TIMING CHARACTERISTICS (Cont’d)
Notes:
1. Resonator characteristics given by the ceramic resonator manufacturer.
2. t
quick V
3. Resonators all have different characteristics. Contact the manufacturer to obtain the appropriate values of external
components and to verify oscillator performance.
4. 3rd overtone resonators require specific validation by the resonator manufacturer.
