I'm trying to interface an RJ-45 connector with a standalone ENC28J60 ethernet controller IC and the manufacturer provided the attached circuit diagram in the datasheet.
I've encircled the bits I need some help with. Firstly the symbol at the bottom is something I've never seen before. I'm guessing it's something similar to a ground but I'm not quite sure? Secondly what's the use of the 1:1 current transformers? Can I simply omit them since they aren't altering the current or voltage in anyway? Or are they a safety precaution to physically isolate the RJ-45 connector from the ethernet controller?
Thanks in advance.
