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
Figure
NOTE:
• E3 rate – ITU-T G.823 and ETSI TBR24 contain frequency masks for input
• DS3 rate – ITU-T G.823 and Bellcore GR499 specify jitter tolerance
• STS-1 rate – Bellcore GR253 specifies a jitter tolerance. It is noted that the
jitter tolerance.
To meet jitter transfer requirements for loop-timed operation, an external
jitter attenuator is required. The jitter attenuator lessens jitter from the
receive clock.

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