Hello Muhammed

I notice that the cristal FA-128 25.000MF20X-K0 from Epson should have 20pF CL.

This means approx. CL1 = 33pF & CL2 =33pF if I add few pF for PCB track.

I'm a bit worried why the capacitance on this cristal is that high?

Can you see any potential problem?

Many other crystals like Murata and so on have CL=6pF-10pF
