Hi! i'm a newbie "engineer" who is trying to design an high throughput (10Gbps) communication channel between a Xilinx FPGA and a PC using a optical medium.

On the pc side i've decided to use the Intel® Ethernet Server Adapter X520-DA2 coupled with an Avago AFBR-703SDZ, and on the FPGA side also an Avago AFBR-703SDZ.

I need to design ethernet protocol to transmit data to PC.
This open core project seems to me well fitting my design:

but what about the PHY ethernet layer? is there any open core or shall i look for an IC?

Thank you!! :)

hi kaiyu

I think you need to buy some IC like the SMSC LAN83C185, that's the IC in charge of Physical layer in Spartan3E Starter Kit.
Good Luck. ;)

Thank you for repling! Supposed that i'll find a 10Gbps PHY ethernet IC, it will be "easily" matched to the ethernet MAC IP core right? Is there any constrain i should pay attention to? Thanks!
