4.3
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
by the quartz specifications given by the quartz manufacturer.

Examples
5.1 MHz
10.18 MHz
These values may be obtained by putting two capacitors in series to the quartz, such as 18 pF and 22 pF in the
5.1 MHz case and 18 pF and 12 pF in the 10.2 MHz case.
