Hi,
I was hoping someone could check these connections for me. I have an RJ45 socket as specified in this diagram:
https://www.electro-tech-online.com/custompdfs/2008/09/0900766b807c5bb0.pdf
And I also have a ethernet controller chip from MicroChip as specified in this datasheet:
https://www.electro-tech-online.com/custompdfs/2008/09/39662c.pdf
If you look at page 9 (or 7 in PDF file) of the MicroChip datasheet you will see a circuit diagram for connecting the outputs from the ENC28J60 to an RJ45 socket. The question I have is that my RJ45 socket contains all the required external peices already for the ENC28J60....I just want to know what wires go with what on the socket.
So far I have:
Can I just leave pins 2, 5, 7, and 8 unconnected on the RJ45? I'm thinking I need to connect up the Center-Tap connections so I can add a Ferrite Bead in there as well....I'm a bit confused as to how to do this though.
Thanks,
Craig

TPOUT+ 1 - TDP
2 - TCT
TPOUT- 3 - TDN
TPIN+ 4 - RDP
5 - RCT
TPIN- 6 - RCN
7 - NC
8 - ?
