You have to be careful here because xPCS supports much more than these interfaces and speeds. I would implement this thinking about the future integrations and leaving margin for more speeds. As for this being a converter I'm not sure about the implementation logic because sometimes you can have a setup like: MAC <-> xPCS <-> SERDES <-> SFP SERDES and SFP may not require configuration nor even have MDIO access so in my view the "PHY" would then be the xPCS, no ? --- Thanks, Jose Miguel Abreu
