Hi,
I've been learning and experimenting with the Virtex 5 Embedded Tri-mode Ethernet MAC Wrapper. It is a core that lets you pick how the MAC is connected to the PHY layer.
I understand the differences between GMII, MII, SGMII, and RGMII, but I am not sure which is best for my design.
Here is my reasoning. Please comment if you agree/disagree.
I am ruling out MII by itself as I need to support GbE.
RGMII and SGMII reduce pin count by adding other components. If I am not short on pins, are there any other advantages?
Thanks!
