We are using LS1043A, in that SerDes Lane A as configured as XFI and routed through a backplane to another Daughter card(same board works for Redundant purpose in our system) where the destination is also LS1043A.

If we route XFI of LS1043A in above senario will that work in 10Gb/s? Can the speed be achieved? Do we need to take any precautions while routing it? 

[bpe · Accepted solution]

In short, yes, direct connection is possible and the maximum speed can
be achieved. More detailed recommendations require making references
to NDA materials and cannot be placed here. Consider opening a
support case:

Thanks for your clarification.

We do have existing NDA with NXP, can you tell me how can you share those documents?

We have not connected any device in between. Interface will be like this XFI from LS1043A of Board A to XFI of LS1043A of Board B  connected through a Backplane. Kindly update me can we achieve 10Gb/s in this connection?
