ITU-T G.823 standard specifies that the clock and data recovery unit must be able to tolerate jitter up to certain
specified limits. Figure 28 shows the tolerance curve.
E3 Jitter Tolerance Requirements
As shown in the Figures above, in the jitter tolerance measurement, the dark line indicates the minimum level
of jitter that the E3/DS3/STS-1 compliant component must tolerate. Table 8 below shows the jitter amplitude
versus the modulation frequency for various standards.
