•
Room for the alignment markers is created by periodically deleting IPG
•
Contains BIP field
•
After all PCS lanes are aligned and deskewed, the PCS lanes are multiplexed
together in the proper order to reconstruct the original stream of blocks and the
alignment markers are deleted from the data stream. As part of the alignment
marker removal process, the BIP3 field is compared to the calculated BIP value
for each PCS lane
•
Once in lock, a lane will go out of alignment marker lock if four markers are
received in a row that do not match the alignment marker that the lane is
currently locked to
Skew
•
Skew (or relative delay) can be introduced between lanes by both active and
passive elements of a link
•
Skew is defined as the difference between the times of the earliest PCS lane and
latest PCS lane for the one to zero transition of the alignment marker sync bits
•
Note that the sync headers and alignment markers are added to the stream so
that the receive PCS can align and deskew the PCS lanes
