13.4.3 Important Information For Calculating Component Values
13.4.3.1 How to Use This Information
MC68HC912DT128A — Rev 4.0
MOTOROLA
Before attempting to apply the information in section
Parameters, the following data from the resonator vendor is required:
The following tables provide Maximum ESR vs. component value for
various frequencies. This table should be used in the following manner:
1. Choose the set of component values corresponding to the correct
2. Determine the range of components for which the Maximum ESR
3. Within this range, choose the EXTAL–XTAL capacitance closest
4. If the ideal component is between two valid component values (the
5. Choose the size of the XTAL–VSS capacitance equal to the
