values on either side and extrapolate.
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.
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.
