JITTER GENERATION
Jitter Generation Definition
Bellcore TR-NWT-000499 (Issue 4), section 7.3.3 "Jitter
generation is the process whereby jitter appears at the output
port of an individual unit of digital equipment in the absence of
applied input jitter."
Jitter Generation Requirement
Bellcore TA-NWT-000253 (Issue 2), section 5.6.5.2 "For
Category II interfaces, jitter generation shall not exceed 0.01
UI rms. For OC-N and STSX-N interfaces, a high-pass
measurement filter with a 12kHz cutoff frequency shall be
used." The low-pass cutoff frequency of the measurement
filter shall be higher than 5MHz.
The characteristic of the measurement filter is shown
below.
