Here are the Stateye v5.080111 results on all channels with these settings
(as discussed in last week's SAS Physical WG meeting):
amp=850 mV
deemp=2 dB
dfe=3 taps
DJ=0.10
RJ=0.15/14
6 Gbps
8b10b
All channels pass if the requirement for the statistical eye is:
amplitude >= 84 mV
jitter <= 0.6 UI
So, these values will be proposed as a SAS-2 letter ballot comment.
