I350 MAC to MAC and PCIE x1 to 4 SGMII ports

85 Views

Hello,

I have a few questions regarding the Intel I350 Ethernet controller:

Can I establish a MAC to MAC link via SGMII without an Ethernet PHY?
I read in the datasheet that I can connect the I350 module to a PCIe x1 slot. I intend to use the I350 as a bridge in the following configuration: PCIe x1 on one side and 4 SGMII channels on the other. Is this feasible?

Additionally, I'm unclear about the PCIe function. I couldn't find specific information about its function.

Could you please refer me to an application note or any other resource where I can find useful information?

I don't have any issue about SOM or FPGA which I will use.

Best regards,
Mihailo Grahovac
