MII to RMII

Other Parts Discussed in Thread: TLK105L

Hey,

I'm thinking of connecting a Controller with MII interface and Wifi module with RMII interface using TLK105L PHY making use of transformerless operation, Is it possible to do so?

Can we connect RMII to MII?

By doing so, is there any timing issues at TD+, TD-, RD+ & RD- as 25MHz for MII and 50MHz for RMII is used.

Appreciate the Help,

Thank YOU

Could you share a block diagram of your proposed connections? From the text description, it is unclear to me what your proposed implementation would look like.

OK. Understood. The MII or RMII interface is specific to the MAC interface. The MDI interface (TD+, TD-, RD+, RD- ) will have the same characteristics and will be interoperable regardless of whether the MAC interface is configured for MII or for RMII.
