Notes:

1. Crystals which require load capacitances of 6, 8, or 10 pF should use the device’s internal load capacitance for

optimum performance. A crystal with a 12 pF load capacitance requirement should use a combination of the internal 10

pF load capacitance in addition to external 2 pF load capacitance (e.g., by using 4 pF capacitors on XA and XB).

ClockBuilder Pro can be used to configure the internal load capacitors.

2. Refer to “AN551: Crystal Selection Guide” for more details.
