Jitter tolerance experiments on 2.5, 3.125 and 10 Gb/s
Hi all
I have made a PDF (ZIPed to 398 kB) document describing experimental Jitter
tolerance measurement on 2.5, 3.125 and 10 Gb/s CDRs. I don't know if this
will pass the reflector. (it didn't).
David Law has put in on the reflector.
THe links is:

ents/jtolerance1.pdf
It also investigates the impact of different signal conditions and the
difference between ITU-T (1 dB optical receiver sensitivity penalty) and the
FC / 10 GE total jitter (TJ) specification.
The recently D2.1 changed TJ of the XAUI high frequency jitter specs to TJ
(incl SJ) of 0.7 UIpp may be difficult to fulfil for a PLL based CDR, even
under ideal signal conditions at that speed of 3.125 Gb/s.
