2.2.8.1. EMACs

The three EMACs are based on the Synopsys* DesignWare® 3504‑0 Universal 10/100/1000 Ethernet MAC and offer the following features:
  • Supports 10, 100, and 1000 Mbps standard
  • PHY interfaces supported through the HPS I/O pins:
    • Reduced media independent interface (RMII) and Reduced gigabit media independent interface (RGMII) through the HPS I/O pins
  • PHY interfaces supported using adapter logic to route signals to the FPGA I/O pins:
    • Media independent interface (MII), Gigabit media independent interface (GMII), RMII, and Serial gigabit media independent interface (SGMII) (with external conversion logic) through the FPGA pins
    Note: The SoC device does not support adapting the HPS EMAC signals to RGMII using FPGA I/O pins.
  • Integrated DMA controller
  • Supports IEEE 1588-2002 and IEEE 1588-2008 standards for precision networked clock synchronization
  • IEEE 802.3-az, version D2.0 of Energy Efficient Ethernet
  • Supports IEEE 802.1Q Virtual local area network (VLAN) tag detection for reception frames
  • PHY Management control through Management data input/output (MDIO) interface or I2C interface
  • 4 KB TX FIFO and 16 KB RX FIFO RAM
  • Supports a variety of address filtering modes
