CI in series with the crystal may be used to adjust the oscillator output frequency· Value may range between 20 pF and 0.01 µ¥, or may be a trimmer capacitor and will approximately equal the crystal load capacitance. X values are approximate and can vary for most circuits and frequencies; this is also true for resistance values. Adequate power supply decoupling is required; local decoupling capacitors near the oscillator are recommended.

All leads should be extremely short in high frequency circuits.
