iMX8M MAC to MAC Communication

Hi,

We are working on one project and want to do MAC to MAC communication.

Requirement: iMX8M to iMX8M communication over MAC.

We have done following connections in the schematic:

MAC1_TxC --> MAC2_RxC

MAC1_Tx_CTL --> MAC2_Rx_CTL

MAC1_TxD[3:0] --> MAC2_RxD[3:0]

MAC1_RxC <-- MAC2_TxC

MAC1_Rx_CTL <-- MAC2_Tx_CTL

MAC1_RxD[3:0] <-- MAC2_TxD[3:0]

We have used external 125MHz clock source. So my question is, where do we have to connect the external clock source??

Do we have to connect to both MAC1_TxC & MAC2_TxC??

If yes, Can we use the same clock oscillator to connect to both MAC1_TxC & MAC2_TxC??

Anything else need to be taken care?

Please confirm on above.

Awaiting for your quick response.

Thanks & Regards,

Sahil Nayak

Hi Sahil

I think connections are correct and one can use the

same clock oscillator to connect to both MAC1_TxC & MAC2_TxC.
