Hello,

I am thinking of using Gigabit Ethernet to have chip to chip interconnection.
How can I achieve this? Can I connnect Chip A to Chip B by SGMII without physical layer in between?

Chip A (GEMAC) -------> Chip B (GEMAC)
______________SGMII_______________

Thanks!
 

Yes it is possible, but you need chips with PHY and MAC mode SGMII interfaces, one chip with PHY mode other with MAC mode.
 

Hello dainis,

Thanks for your reply.
Can you tell me what IP can be implemented into a FPGA as PHY mode?
Since I am using Xilinx`s FPGA which doesn`t support SMII.
I would like to use SGMII and run at 100Mbps only to connect from FPGA A to FPGA B.

Best Regards,
MelonPie
 

After small thinking, I got answer that is possible connect two chips directly without PHY or switch chip, by using SGMII or MII intefaces with MAC mode.
Look this:
