Remarks on defining the External Load Capacitance:
External capacitors at each crystal pin to ground are required. They are necessary to tune the effective load
capacitance of the PCBs to the required load capacitance (C
L
) of the crystal. The higher the capacitors, the
lower the clock frequency results. The nominal free running frequency should match f
p
= 20.25 MHz. Due to
different layouts of customer PCBs, the matching capacitor size should be determined in the application. The
suggested value is a figure based on experience with various PCB layouts.
Tuning condition: Code DVCO Register =

2)
Remarks on Pulling Range of DCO:
The pulling range of the DCO is a function of the used crystal and effective load capacitance of the IC (C
ICLoad
+ C
LoadBoard
). The resulting frequency (f
L
) with an effective load capacitance of C
