Maximum Output Jitter In Absence of Input Jitter
CCITT Recommendation G.823 specifies that it is necessary to restrict the amount of jitter generated by indi-
vidual equipments. The actual limits depend on the type of equipment (and application).
In the absence of applied jitter, the receive path of the MRT introduces a maximum 0.05 Unit Intervals (UIs)
peak-to-peak jitter over the following frequency ranges:
At 8.448 Mbit/s: 20 Hz to 400 kHz
At 34.368 Mbit/s: 100 Hz to 800 kHz
This operation is with the MRT terminated by the external components (and component values) specified in
the Pin Description Table for pin 7 (VCOC), pin 17 (PLLC), and pin 22 (AGFIL).
Jitter Transfer
Transfer of jitter through an individual equipment is characterized by the relationship between the applied input
jitter and the resulting output jitter as a function of frequency. CCITT Recommendation G.823 specifies that it is
important to restrict jitter gain.
With applied input jitter at the MRT receive terminals, the maximum MRT output jitter is not greater than the
level of input jitter plus 0.05 UI peak-to-peak jitter.
This operation is over the same CCITT specified frequency ranges and MRT external terminations as
described in the above Maximum Output Jitter section.
Interfering Tone Tolerance
The MRT will properly recover clock and present error-free output to the receive terminal side interface in the
presence of a PRBS interfering tone with the same data sequence as the data input for the following line rates:
*PRBS = Pseudo-Random Binary Sequence
