Attached are plots showing a proposed refinement to the XAUI compliance
channel limit.
Some comments received on the first proposal (red line) have been addressed
(green line):
1. Skin effect was not well represented. It now dominates below 1 GHz.
2. The ISI loss was not sufficient. It is now 4 dB, as agreed to at the last
Interim.
3. The low frequency loss was less than most of the data. It is now near the
middle of the measured data.
The refined coefficients are:
a1 = 6.5e-6
a2 = 2.0e-10
a3 = 3.3e-20
