variation or particle contamination).
3. Within this range, choose the EXTAL–VSS capacitance closest to
(C_{EXTAL–VSS} = 2*CL – 10pF).
4. If the ideal component is between two valid component values (the
maximum ESR is sufficient for both component values), then
choose the component with the highest maximum ESR or choose
an available component between the two listed values.
5. Choose the size of the XTAL–VSS capacitance equal to
EXTAL–VSS capacitance.
6. If the frequency of the crystal falls between listed values,
determine the appropriate component for the listed frequency
values on either side and extrapolate.
7. The maximum allowed capacitor is the highest listed component,
and the minimum allowed capacitor is the lowest listed
component. ‘NA’ or ‘Not Allowed’ means the listed component is
not valid or allowed for the given frequency, Shunt Capacitance,
and VDDPLL setting.
12.5.3.2 General Specifications
The following limitations apply to every system:
• Ceramic resonators with integrated components must have the
integrated components accounted for in the total component
value.
• Series cut resonators should not be used. Use parallel cut instead.
• The Load Capacitance should be 12pF or higher, preferably
greater than 15pF.
