This is especially important for bus cycles using waitstates and e.g. for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
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
f
MC
cycles (TCM).
For a period of
N
×
TCM the accumulated PLL jitter is defined by the deviation D
N
:

[ns] =

/

);
f

in [MHz],
N
= number of consecutive TCMs.
So, for a period of 3 TCMs @ 20 MHz and K = 12: D

=
±
(1.5 + 6.32
×
3
/ 20) = 2.448 ns.
This formula is applicable for K
×
N
< 95. For longer periods the K
×
N
= 95 value can be
used. This steady value can be approximated by: D
Nmax
[ns] =
±
(1.5 + 600 / (K
×
f
MC
)).
