The jitter attenuator meets the jitter transfer requirements of ITU-T I.431 and G.735-739
(refer to
Figure 11
Also the requirements of ETSI TBR12/13 are satisfied. The DCO starts jitter attenuation
at about 2 Hz to ensure adequate margin against TBR12/13 output jitter limit with 15 UI
input at 20 Hz.
Data Sheet
The DCO can be used either in receive or transmit direction (see
If flexible clocking mode is selected (GCM2.VFREQ_EN = 1), the SYNC frequency can be selected
independent of E1 or T1/J1 mode.
