This example design targets the Xilinx VCU108 FPGA board.
The design places a looped-back MAC on the BASE-T port as well as a looped-back UART on on the USB UART connection.
The design places looped-back MACs on the BASE-T and QSFP28 ports as well as a looped-back UART on on the USB UART connection.
* USB UART
* Looped-back UART
* RJ-45 Ethernet port with Marvell 88E1111 PHY
* Looped-back MAC via SGMII via Xilinx PCS/PMA core and LVDS IOSERDES
* QSFP28
* Looped-back 10G or 25G MACs via GTY transceivers
## Board details
* FPGA: xcvu095-ffva2104-2-e
* 1000BASE-T PHY: Marvell 88E1111 via SGMII
* 25GBASE-R PHY: Soft PCS with GTY transceivers
## Licensing
