The loop bandwidth f
typical values are 50. ζ = 0.9 ensures a good transient response.
And finally the frequency relationship is defined as
With the above values the resistance can be calculated. The example is shown for a loop bandwidth
f
The capacitance C
The capacitance C
A.4.3.2
The basic functionality of the PLL is shown in
deviation from the reference clock f
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
