4.7.13.1.1
The total phase jitter on the reference clock is specified at 3 ps RMS. There are numerous ways to measure
the reference clock jitter, one of which is as follows.
Using a high-speed sampling scope (20 GSamples/s), 1 million samples of the differential reference clock
are taken, and the zero-crossing times of each rising edge are calculated. From the zero-crossing data, an
average reference clock period is calculated. This average reference clock period is subtracted from each
sequential, instantaneous period to find the difference between each reference clock rising edge and the
ideal placement to produce the phase jitter sequence. The power spectral density (PSD) of the phase jitter
is calculated and integrated after being weighted with the transfer function shown in
root of the resultant integral is the RMS total phase jitter.
