From serial PMD call 5 June
Jitter spec numbers
-------------------
Opinion on the call was that:
0.35 UI of DJ was too much; nearer 0.3 UI would be fairer
0.015 UI of sigma_RJ was too little; 0.016 suggested
The extra 0.05 UI of sinusoidal jitter in the stressed sensitivity test was
a significant burden.
Some believed that our draft jitter requirements are more demanding than
SONET.
Anthony Sanders suggested that the stressed eye should contain the
sinusoidal jitter as a component of the deterministic jitter, rather than in
addition to it. SJ is more stressful than "regular" DJ as its probability
distribution is concentrated towards the extremes. As these minutes may not
represent the ideas correctly, Anthony would put some slides on the
reflector for discussion. Also Ali Ghiasi may be able to offer some
information on CDR requirements (how many UI of eye opening needed).
Next Draft
----------
Is expected 11 June.
