Capacitor values are for design guidance only:
These capacitors were tested with the resonators
listed below for basic start-up and operation. These
values are not optimized.
Different capacitor values may be required to
produce acceptable oscillator operation. The user
should test the performance of the oscillator over the
expected VDD and temperature range for the
application.
See the notes following Table 8-2 for additional
information.

Capacitor values are for design guidance only:
These capacitors were tested with the crystals listed
below for basic start-up and operation. These values
are not optimized.
Different capacitor values may be required to
produce acceptable oscillator operation. The user
should test the performance of the oscillator over the
expected VDD and temperature range for the
application.
See the notes following this Table for additional
information.
Crystals Used(3):
4.0 MHz
8.0 MHz
20.0 MHz
Note 1:
While higher capacitance increases the
stability of the oscillator, it also increases
the start-up time.
2:
Since each resonator/crystal has its own
characteristics, the user should consult
the resonator/crystal manufacturer for
appropriate values of external
components.
3:
RS may be required to avoid overdriving
crystals with low drive level specification.
4:
Always verify oscillator performance over
the VDD and temperature range that is
expected for the application.
