Dear all,

I am trying to understand exactly what kind of SP
is going on the Rx and Tx path of the FPGA and basic
Rx/Tx.

I am attaching an eps file (and an xfig file) with a hypothesized block
diagram that is the result of all the information I have
collected on the website and the discussions.

Can you comment on that and tell me if this is
exactly what is going on?


Thanks
Achilleas
