Part Number: DP83848J

Hi,

I would like to check what manner can trigger or enable DP83848JSQ/NOPB to function phy transmit and receive? By RMII signals only? By other way?

    Hi Jim,

    I am not sure I quite understand your question. Could you clarify a bit more? When the PHY is powered on correctly, once it receives packets from the MAC, it will transmit the data to the MDI, and vice versa. The DP83848 can support the MII and RMII MAC interface and the copper MDI interface.

    Regards,
