I210 - unused MDI pins when configuring 100BASE-T

I am using the I210IT in my design as a fixed 100BASE-T controller. As there are only two transformers used which are connected to MDI-0 and MDI-1, the MDI-2 and MDI-3 pins are not in use. Can I leave these unused pins open or do I have to terminate them?

Hi Bert_L,

 

 

Thank you for posting in Wired Ethernet community.

 

 

After reviewing your question, it involved integrating Ethernet controller to your system. We'd suggest posting your query in our embedded community to confirm if the unused pins need to be terminated in your configuration. There's an ongoing thread about I210 unused pins.

Hope this helps.
