I need to connect multi phy device with a single cpu. I want realize a follow hardware (see picture MultiPhys.jpg ). My dubt is if this schematic is correct. I need to send frame either PHY1 or PHY2. My application is like a gateway, it sends messages to network in selective way ( and it receives from every PHYs device ). Is it possible connect many PHY device with one RMII bus? what is the correct way to connect many PHY device on RMII bus?

Anyone knowns documents that describe multi Phy configurations ?

Hi

It is not possible to connect multiple PHYs to a single Ethernet connection (they will short circui each other).

It is however possible to use a multiple-port PHY such as the Micrel KSZ8863 to achieve multiple Ethernet connection (see its tail-tagging mode).

Regards
