External Crystal Load Capacitance (parallel resonant)2
2. CL refers to the total load capacitance as specified by the crystal manufacturer. Crystals that 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.
