MagJack means the isolation transformers (the magnetics every Ethernet port needs) sit inside the socket, so your Ethernet chip's transmit and receive pins connect straight to the header.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe socket is the \u003cstrong\u003eHanRun HR913550A\u003c\/strong\u003e for \u003cstrong\u003e10\/100 Mbit\u003c\/strong\u003e Ethernet.
