1) Not subject to production test, verified by design/characterization.
2) The PLL jitter characteristics add to this value according to the application settings. See the PLL jitter parameters.
3) The PLL jitter is not included in this parameter. If the BFCLKO frequency is equal to fCPU, the K divider has to be regarded.

EBU Asynchronous Timings
For each timing, the accumulated PLL jitter of the programed duration in number of clock periods must be added
separately.
