Dear Experts,
I found the following Jitter Tolerance Specification for XAUI:
Receiver must be able to tolerate this much jitter
DJ : 0.37 UIp-p
DJ+RJ : 0.55 UIp-p
SJ : additional SJ (on top of DJ+RJ) to limit of mask…
-> 8.5 UI < 22.1kHz
-> 0.1 UI > 1.875MHz (linear fit between these points)
legend:
DJ : Deterministic jitter (includes residual ISI, duty-cycle error, etc.)
RJ : Random jitter – uncorrelated with any source
SJ : Sinusoidal jitter
Is there any formula or rule of thump, how much SJ the receiver must tolerate,
if one could reduce the DJ and RJ to neglegible values?
Thanks in advance,
Ralf
