3.3 Gigabit Ethernet Interface

The AX7Z035B development board has two Gigabit Ethernet interfaces, one of
which is connected to the PS system, and the other one is connected to the logical
IO ports of the PL. The Gigabit Ethernet interface connected to the PL side needs to
be mounted to ZYNQ's AXI bus system via program calling IP.
The Ethernet chip adopts JL Semiconductor's industrial-grade Ethernet GPHY
chip (JL2121-N040I) to provide network communication services for users. The
Ethernet PHY chip on the PS end is connected to the GPIO interface of ZYNQ's PS
