The jitter attenuator meets the jitter transfer requirements of the recommendations I.431
and G.735-739 (refer to
Figure 13
Also the requirements of ETSI TBR12/13 are satisfied. Insuring adequate margin against
TBR12/13 output jitter limit with 15 UI input at 20 Hz the DCO-R circuitry starts jitter
attenuation at nearly 2 Hz.
