Green LED connected to MIO8
Ethernet
The TE0782 is equipped equipped with two Marvell Alaska 88E1512 Gigabit Ethernet PHYs (U18 (U3 ETH1) and has in this TRM the identifier Ethernet0. The Ethernet0 PHY RGMII Interface is connected to the Zynq ETH0 PS GEM0. The U20(ETH2)). The I/O Voltage is fixed at 1.8V for HSTL signaling.
SGMII (SFP copper or fiber) can be used directly with the Ethernet PHY, as the SGMII pins are available on the B2B connector J2.
The reference clock input of the PHY is supplied from an on board 25MHz oscillator (U10).
. The reference clock input for both PHYs is supplied from an on board 25MHz oscillator (U11).

The TE0729 SoM is also equipped with two additional Microchip KSZ8081MLXCA Ethernet-PHYs (ICs U17 and U19) to provide further 10/100 Mbps Ethernet interfaces with the identifiers Ethernet1 and Ethernet2. Those PHYs can be operated as Ethernet interfaces 10Base-T or 100Base-T with for 4-wires twisted pair cable. The reference clock input of both PHYs is supplied from the same 25MHz oscillator (U10), which also provides Ethernet0 Gigabit PHY with a reference clock signal.
