The PLL does not filter typical spread-spectrum input clocks because they are usually far below the bandwidth filter frequencies.
The static offset is measured between any PLL outputs with identical phase.
Values for this parameter are available in the Clocking Wizard.
Includes global clock buffer.
Calculated as F VCO /128 assuming output duty cycle is 50%.
