Ethernet Circuit
The IC201 is used for the Ethernet interface.
It is connected from (IC201) to the Ethernet port(JK1 and JK2) through a transformer and so is isolated.
Also, LAN port (JK1) gets power from the Ethernet line For PoE (Power over Ethernet) as shown below.
It is connected between (IC201) and the BBIC(IC302) by high-speed bus called RMII(Reduced Media Independent Interface)
bus operating with 50MHz.
