Important NotesAlways handle the crystal oscillator with care to avoid damage from static electricity or mechanical stress.
Ensure that the crystal oscillator is properly connected to the target device and that the device is configured to use the external clock signal.
The frequency of the crystal oscillator may vary slightly due to manufacturing tolerances. For critical applications, it is recommended to use a crystal oscillator with a tighter frequency tolerance.
