Replace MAC block with SGMII

Hi All, I have a MII interface with 10/100 support in which MAC block is used as IP in my design. I am doing feasibility study of removinf MAC block to external L2 component and use SGMII...

I am a bit confused by your post.

Are you saying that you currently have a 10/100 MAC with an external MII interface in your FPGA and that you want to replace it with a 10/100/1000 MAC with an external SGMII interface?

You will always need a MAC function whether you use MII or SGMII. For Gigabit Ethernet the standard interface is GMII but this is converted to SGMII etc by an additional function called PCS. This sits between the MAC and external PHY.

Have you had a look at the Altera Triple Speed Ethernet MAC (TSE)? It might be what you are after

Hope this helps
