2.4 Jitter Tolerance

The CX2833i receiver is able to tolerate a specified amount of high-frequency

jitter in the received signal while providing error-free operation (generally

defined as a bit error rate of less than 10-9). The specifications (illustrated in

Figure 2-9) for jitter tolerance are discussed in the following documents:

•

E3 rate – ITU-T G.823 and ETSI TBR24 contain frequency masks for input

jitter tolerance.

NOTE:

To meet jitter transfer requirements for loop-timed operation, an external

jitter attenuator is required. The jitter attenuator lessens jitter from the

receive clock.

•

DS3 rate – ITU-T G.823 and Bellcore GR499 specify jitter tolerance

frequency masks for Category I and Category II interfaces.

•

STS-1 rate – Bellcore GR253 specifies a jitter tolerance. It is noted that the

STS-1 jitter tolerance differs from DS3 requirements only for Category II

interfaces.
