Ethernet Circuit
The IC201 is used for the Gigabit Ethernet interface.
It is connected from (IC201) to the Ethernet port(JK201 and JK202) through a transformer and so is isolated.
Also, LAN port (JK201) gets power from the Ethernet line For PoE (Power over Ethernet) as shown below.
It is connected between (IC201) and the BBIC(IC101) by high-speed bus called RGMII(Reduced Gigabit Media Independent Inter-
face) bus operating with 25MHz.
