4.1.7
J
itter Tolerance
The TE3-LIU receiver’s tolerance to input jitter complies to and exceeds the relevant
international standards. Especially the requirements of Telcordia GR-499-CORE (DS3),
ITU-T G.824 (DS3), GR-253-CORE (STS-1) and ITU-T G.823 (E3) are fulfilled and
exceeded.
Figure 11
and
Table 10
show the different input jitter specifications. Low
frequency jitter is called
"
wander
"
, where the defined border between jitter and wander
is 10 Hz for DS3/E3 and 100 Hz for STS-1.
