I have a switch that has a 4 wire (2 twisted pairs) ethernet interface which I want to connect to an i.MX8 Plus MPU (GBit ethernet with 4 pairs). I need to design the PCB that connects the MPU to the connector.
- Can I just route the two pairs needed to a 4 pin connector (like on the switch)?
- Do I need to terminate/disable the two unused ethernet pairs or can I just not connect them?
Thank you for your help.
