Table 63.
The PLL input frequency range is limited to 1 to 3.5 MHz, while the VCO oscillation range is
64 to 128 MHz. The CPU clock frequency range when PLL is used is 16 to 40 MHz.

PLL Input Frequency = 2 MHz

PLL Output Frequency = 40 MHz (VCO frequency divided by 2)
f
Self referred single period jitter
Also called “Period Jitter”, it can be defined as the difference of the T
where T
time period of the PLL output clock.
Self referred long term jitter
Also called “N period jitter”, it can be defined as the difference of T
T
minimum time difference between N + 1 clock rising edges. Here N should be kept
sufficiently large to have the long term jitter. For N = 1, this becomes the single period
jitter.
