RXAUI 8b/10b coding before interleave or interleave before coding

Jump to solution

Hi everyone

Now I am debugging the connection between the phy IC and the rxaui PCS/PMA.

the phy IC  apply 8/10 encoding first and then interleave at the 10bit level as default , but the pg083 just  descriped as follow " the data on each lane is 8B/10B encoded before transmission " Does it mean that the coding before interleave ?

 

after I changed the setting to " interleave two 8bit stream first and then apply 8/10 encoding',the connection between phy IC and  rxaui PCS/PMA success.

 

So my question is that whether the rxaui uses coding before interleave  or not!

Hi

 

The core interleaves the two channels and then 8b10b encoding is done in the transceivers

I believe the interleaving is meant to happen at the 10B level.

 

I would refer you to the specification, but I can't find an online link on Marvell's website right now.  There seems to be a copy cached at Opencores though.

I'm curious - when the Xilinx core was tested, what was it tested against?
