# W5500 And POE RJ45 with no RCT and TCT

## Question

Asked by Adam Glynn on 2024-03-26 in Ethernet Chips.

I know a post like this has been made, but the links to solutions seem to have been deprecated.

I would like to use the W5500 chip on my board, as well as a PoE controller (Si-3404), but I’m finding it very difficult to find an RJ45 connector with TCT and RCT pins. Is it possible to configure the W5500 with only a CT pin on the RJ45 connector?

If so, can someone help with the change in schematic please?
