Hi,


Yes, you need to write RTL logic for MAC+PCS & MDIO logic as well for external PHY's then you can directly connect it with XCVR Native PHY 2.5G.

Hi Tiwari,

I am very grateful for your information; it has been very helpful to me.

However, I have some additional questions. There is already a Standard PCS within the Native PHY. When I select GigE 2.5G, it sets up to enable PCS 8b/10b. How is this different from the PCS you mentioned? Specifically, what additional PCS functionality do I need to implement? Could you provide some hints?

Are you referring to handling things like Ordered-sets?

Thank you very much.
