E3 Jitter Tolerance Requirements:
ITU-T G.823 standard specifies that the clock and data recovery unit must be able to accommodate and toler-
ate jitter up to certain specified limits. Figure 23 shows the tolerance curve.
As shown in the Figures 22 and 23 above, in the jitter tolerance measurement, the dark line indicates the mini-
mum level of jitter that the E3/DS3/STS-1 compliant component must tolerate.
The Table 11 below shows the jitter amplitude versus the modulation frequency for various standards.
6.0.2
JITTER TRANSFER - RECEIVER/TRANSMITTER:
Jitter Transfer function is defined as the ratio of jitter on the output relative to the jitter applied on the input ver-
sus frequency.
