REV. 1.0.4
ITU-T G.823 standard specifies that the clock and data recovery unit must be able to tolerate jitter up to certain
specified limits.
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.
versus the modulation frequency for various standards.
