2.6.2 Crystal Oscillator

For Crystal Oscillator Connections, refer to the Schematic Checklist section of the data sheet.

The crystal must be located as close to the device as possible. Long signal lines may cause too high load to operate the crystal, and cause crosstalk to other parts of the system.

Important: Crystal selection must be done using the “Crystal Data Sheet” and the “Crystal Oscillator Parameters” given in the XOSC Electrical Specifications from the Electrical Specifications chapter.
