Quartz Load Capacitance Calculation
The value of the capacitor necessary to achieve that the quartz oscillator is
operating at the intended frequency is determined by the reactive part of the
negative resistance of the oscillator circuit as shown in Section 5.1.3 and by the
quartz specifications given by the quartz manufacturer.

the load capacitance (refer to the quartz crystal specification).
Example:
13.4 MHz: C

= 5.9 pF
This value may be obtained in high accuracy by putting two capacitors in series
to the quartz, such as 22pF and 8.2pF for 13.4MHz.
