Gigabit Ethernet Port2
The Zynq Ult MPSoC (ZU11/17/19EG) SOM Carrier board supports two 10/100/1000Mbps Ethernet ports. The
second Ethernet port is supproted through GEM3 interface of Zynq Ult MPSoC (ZU11/17/19EG) PS. The MAC
is integrated in the Zynq-Ult MPSoC (ZU11/17/19EG) PS and connected to the external Gigabit Ethernet PHY
“AR8031” on Carrier Board through Board to Board Conn
ector1. This PHY is interfaced with GEM3 interface of MPSoC
’s
PS through MIO pins and works at 1.8V IO voltage level.
The Gigabit Ethernet PHY also supports MDC, MDIO, Reset and Interrupt Signals for control. These signals are used
through PL Bank EMIO pins from Board to Board Connector1 pins 124, 126, 92 & 94 respectively. Ethernet PHY output
is directly connected to RJ45 Magjack (J20). Also it supports Speed (Yellow) and Link/Activity (Green) LED indications
on RJ45 Magjack connector. This RJ45 Magjack connector is physically located at the top of the board as shown below.
