1. Part characterized with the following crystal frequency values: 12.288 and 24.576
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.
