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
