device to replace a WIFI module by Ethernet phy with SDIO interface?

Hi,

I have a design with a WIFI module. The interface between the processor and the WIFI module is a SDIO V2.0 interface.

But, I need to change the WIFI by Ethernet... So I'm looking for a solution (1 or 2 or 3 devices) to make this modification.

The dificulty is to get an ethernet PHY with a SDIO interface, I haven't MII or RMII or SNI (I think those interfaces are not compatible with SDIO).

The SDIO interface is with the pins SDIO_DATA[0..3], SDIO_CMD and SDIO_CLK.

Have you a solution?

Thanks for your help.

    Hi Rozor,

    An SDIO interface is unusual compared to our MII or RMII interface. Conversion between the two seems possible, but an intelligent device will need to do the conversion and negotiation with the SDIO host. I am not aware of any devices to convert between SDIO and MII.

    Best Regards,

    Hi Rod,

    Thanks for your answer.

    After long time to looking for a solution, only one big! It's to use a chip SDIO to USB and a chip USB to Ethernet.... it's like a gaz factory solution :)
