Table 32: Gigabit Ethernet PHY (PL) Configuration - Bootstraps
For the Ethernet PHY configuration via the MDIO interface, the MDC clock frequency must not exceed
2 MHz.
The PHY is configured in single LED mode with active-low LEDs 1 and 2.

RGMII Delays Configuration

The Ethernet PHY (PL) is connected to the PL side of the MPSoC device, to be used in combination with a
soft MAC controller. In order to achieve the best sampling eye for the RX and TX data, it is recommended
to adjust the timing constraints of the FPGA pins and/or the pad skew delays of the Ethernet PHY. Refer
to the Ethernet PHY datasheet for details on how to program the RGMII pad skew registers.
In the Andromeda XZU90 module reference design the RGMII delays are set through timing constraints,
additional the pad delays are configured to provide 2 ns delay on the TX clock signal.

USB 2.0

A USB 2.0 PHY is available on the Andromeda XZU90 module and connected to the PS to MIO bank 502.
The USB PHY can be configured to host, device or On-The-Go (OTG) mode.

USB 3.0

Xilinx Zynq UltraScale+ devices feature two built-in USB 3.0 controllers and PHYs, configurable as host or
device. The PHY interface used by the USB 3.0 controller is PIPE3, supporting a 5 Gbit/s data rate in host
or device mode. The interface of each USB 3.0 controller uses one of the PS GTR lanes.
