Figure 10.2 Formula to Find the Value of C1 and C2
Note 10.1 C0 is usually included (subtracted by the crystal manufacturer) in the specification for CL
and should be set to ‘0’ for use in the calculation of the capacitance formulas in
present a parasitic capacitance between XTALIN and XTALOUT. For an accurate
calculation of C1 and C2, take the parasitic capacitance between traces XTALIN and
XTALOUT into account.
Note 10.2 Each of these capacitance values is typically approximately 18 pF.
1.Only when SEL48 is available and supported.
