RE: delay constraints from XGMII to XAUI

["Grow, Bob" <bob.grow@xxxxxxxxx>]

The only MAC requirement I can think of for bounding the lower layer delay
is for buffer sizing for 802.3x flow control.  That has been the factor for
keeping the delay tables in various clauses.

Subject: delay constraints from XGMII to XAUI




Hi all:

In D2.0 table 48.5 defines the MDI to XGMII delay constraints to be 272
UI.
I wonder that "is there any delay constraints on XAUI to XGMII
(PCS+PMA)"?

thanks

best regards
