External Crystal Load Capacitance (parallel resonant)2
2. CL refers to the total load capacitance as specified by the crystal manufacturer. Crystals which require a CL outside
this range should be avoided. The crystal oscillator circuit design should follow the crystal manufacturer’s
recommendation for load capacitor selection.
