And finally the frequency relationship is defined as
With the above inputs the resistance can be calculated as:
The capacitance C
The capacitance C
The stabilization delays shown in
component selection (e.g. crystal, XFC filter).
A.5.3.2
The basic functionality of the PLL is shown in
deviation from the reference clock f
accordingly.The adjustment is done continuously with no abrupt changes in the clock output frequency.
Noise, voltage, temperature and other factors cause slight variations in the control loop resulting in a clock
jitter. This jitter affects the real minimum and maximum clock periods as illustrated in
