Hi Ria,
When one considers crosstalk due to data pattern, there is inherent randomness
involved. More work is involved in figuring out which pattern(s) cause
crosstalk over limits, whether those patterns are infact valid per channel
encoding rules etc.. And channel crosstalk could also happen between two
independent ICs..
So it becomes difficult to quantize loss when such patterns/conditions do
indeed occur.
Whereas reflection losses on a channel can be established within limits during
link training as part of link negotiation.
So I believe any algorithm to compensate for channel losses would be easier to
do than otherwise.

Gurus,
Is it true that losses due to reflection are easier to equalize on a channel
versus (pattern dependent losses) due to crosstalk?
If so why?
Thanks
Ria
