4.3 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.

Determination of Series Capacitance Value for the Quartz Oscillator
The quartz oscillator input impedance consists of a negative resistance and an
inductance L.
