XAUI/XGXS Question
Hi Rich,
Recalling from your March presentation that the Max skew between two lanes
is 8 Characters (80 bit), and that the distance between two adjacent /A/'s
is 16 Characters.
1.So, in this case, how should one know Which /A/ is this? (That is, if a
certain lane exceeds the other in 8 characters or delayed after the other in
8 characters it looks the same)
2.Suppose some /R/'s were dropped in the middle due to clock tolerance
compensation. The result is that the distance between two adjacent A's is
smaller than 16 characters. In this case its even more problematic to
distinguish between delayed lane to an exceeding one.
Can it be solved by:
1.Enlarging the gap between /A/'s
2.Doing de-skew on the /S/ and /Dxx.y/ code-words
Thank you,
Boaz
