Jitter Information
With each transition of the clock f
, the deviation from the reference clock f
is measured and input
cmp
ref
voltage to the VCO is adjusted 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
Figure
A-5.

The relative deviation of t
is at its maximum for one clock period, and decreases towards zero for larger
nom
number of clock periods (N).
