Jitter generation is defined as the amount of jitter at the STS-N output in the absence of applied input jitter. The
Bellcore and ITU requirement for this type jitter is 0.01UI rms measured with a specific band-pass filter.
Jitter Generation
For more information on these specifications refer to Bellcore TR-NWT-000253 sections 5.6.2-5 and GR-253-
CORE section 5.6.
