Hi, Team:

For the convenience of PCB layout, we swap the P/N of TDP_x and TDM_x interfaced with Magnetics Component.

The connection of my board with PC always fails.

You can see my shematic below:

I am curious if the differential pair P/N can swap ?

Hello,

Thank you for your question. Can you provide the schematic of your magnetic component to the RJ45 connector? This will help me better understand the channel and polarity expected by the link partner?

Regards
Justin

Justin :

I think I get the answer for my question. I read the shematic of the PHY's EVM and find that PHY's MDI interface is also exchange P/N to magnetic component. This means that MDI differential pair can exchange the P/N.

Thank you for you work.

Best Regards
