generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter
is negligible.
The value of the accumulated PLL jitter depends on the number of consecutive VCO
output cycles within the respective timeframe. The VCO output clock is divided by the
output prescaler (K = PLLODIV+1) to generate the master clock signal
f
MC
. Therefore,
the number of VCO cycles can be represented as K
×
N
, where
N
is the number of
consecutive

cycles (TCM).
For a period of

Approximated Accumulated PLL Jitter
Note: The bold lines indicate the minimum accumulated jitter which can be achieved by
selecting the maximum possible output prescaler factor K.
Different frequency bands can be selected for the VCO, so the operation of the PLL can
be adjusted to a wide range of input and output frequencies:
