4.6.3
Jitter generation is defined as the amount of jitter at the STS-N output in the absence of applied input jitter. The
bandwidth is set according to the data rate. The Bellcore and ITU requirement for this type jitter is 0.01UI rms
measured with a specific band-pass filter.
For more information on these specifications refer to Bellcore TR-NWT-000253 sections 5.6.2-5 and GR-253-
CORE section 5.6 and ITUT G.783 section 9.3.1.1. Table 17 below shows the jitter generation limits per
BellCore GR-253 and ITUT G.783 versus XRT91L31 typical jitter performance.
