CL2) + Cstray, where Cstray is the capacitance of the pin and the capacitance of the PCB or

related to the PCB, which is usually between 2pF and 7pF.

Warning: It is recommended to use resonators with load capacitance CL ≤7pF instead of

resonators with load capacitance of 12.5 pF.

For example, if a resonator with load capacitance CL=6pF is selected and Cstray=2pF,

CL1=CL2=8pF
