Jitter Tolerance
The QuadFALC receiver’s tolerance to input jitter complies to ITU for CEPT application.
Figure 13 shows the curves of different input jitter specifications stated below as well as
the QuadFALC performance.

Jitter Tolerance
Output Jitter
In the absence of any input jitter the QuadFALC generates the output jitter, which is
specified in the table below..
Specification
ITU-T I.431
Transmit jitter attenuator
The transmit jitter attenuator DCO-X circuitry generates a „jitterfree“ transmit clock for
each channel and meets the following requirements: ITU-T I.431, G. 703, G. 736-739,
G.823 and ETSI TBR12/13. The DCO-X circuitry works internally with the same high
frequency clock as the receive jitter attenuator it does. It synchronizes either to the
working clock of the transmit backplane interface or the clock provided by pin TCLK or
