Dear team,

 

My customer is trying to use i.MX8M for their product.

And now they are trying to design their proto board.

They have a question about routings between i.MX8M and external Ether PHY chip with RMII.

They intend to use Microchips/ LAN8720A for the PHY.

Could you show me the signal routings between i.MX8M and LAN8720A?

 

[LAN8720A] -------------- [i.MX8M]

REFCLKO -------------- ??

TXD0 ------------------- ??

TXD1 ------------------- ??

TXEN ------------------- ??

RXD0 ------------------- ??

RXD1 ------------------- ??

RXER ------------------- ENET1_RX_ER??

CRS_DV --------------- ??

 

Thanks,

Miyamoto
