Ethernet port #1 (ETH1) - J9[edit | edit source]

J9 is a RJ45 Gigabit Ethernet connector - incorporating magnetics - connected to Micrel KSZ9031 PHY (Gigabit Ethernet Transceiver). This, in turn, is connected to PL's bank 13 via RGMII interface. This is an example of EMIO routing showing how to route PS's MAC signals via PL subsystem.
