REV. 1.0.3
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.
For more information on these specifications refer to Bellcore TR-NWT-000253 sections 5.6.2-5 and GR-253-
CORE section 5.6.
Phase noise plot shows the power of the noise with respect to the carrier power. When this curve is integrated
in the frequency band of interest, the outcome is the noise power. Jitter generation in rms is then derived by
factoring with the appropriate period for the clock cycle.
