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.

S
= 7.2 pF
This value may be obtained by putting two capacitors in series to the quartz,
such as 18pF and 22pF in the 5.1MHz case and 18pF and 12pF in the 10.2MHz
case.
