Default values
In case of using the evaluation board, the crystal with its typical parameters (fp=18.08958MHz,
C
each are used the following default states are set in the device
Table 3-6
3.2.7
Quartz: fp=18.08958MHz; C1=8fF; C0=2,08pF; CL=12pF (typical values)
Cv1=4.7pF, Cv2=1.8pF, Cv3=12pF
Table 3-7
Table 3-8
Tolerance values in Table 3-8 are valid, if pin 21 is not connected. Establishing the connection to
pin 21 the tolerances increase by +/- 20ppm (internal capacitors), if internal tuning is not used.
