Default values
In case of using the evaluation board, the crystal with its typical parameters (fp=13.125MHz,
C
each are used the following default states are set in the device
Table 3-6
3.2.7
Quartz: fp=13.125MHz; C1=6.5fF; C0=1,8pF; CL=20pF (typical values)
Cv1=27pF, Cv2=1.0pF, Cv3=15pF
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 +/- 16ppm (internal capacitors), if internal tuning is not used.
Concerning the frequency tolerances of the whole system also crystal tolerances (tuning
tolerances, temperature stability, tolerance of C L ) have to be considered.
In addition to the chip tolerances also the crystal and external component tolerances have to be
considered in the tuning and non-tuning case.
