These reference value ranges are for after a PLL predivider (PREDIV), which can be programmed to 1, 2, 4, 8, or 16.
The PREDIV value can be set while booting from serial flash. In parallel reset configuration, the PREDIV value is set to
one. In this mode, if the input frequency results in an out of range reference frequency, boot the processor in limp
mode, set the proper PREDIV and multiplier settings, and switch to PLL mode.

Peak-to-peak jitter (clock edge to clock edge)
Long term jitter
8
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal.
Noise injected into the PLL circuitry via PLL VDD, EVDD, and VSS and variation in crystal oscillator frequency increase
the Cjitter percentage for a given interval.
