A 1. Part characterized with the following crystal frequency values: 11.2896, 12.288, 18.432, 24.576, & 27 MH.z.

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

IN recommendation for load capacitor selection.
