The ETH_MAC_10G_SFP IP incorporates one Ethernet MAC at 10Gbits on a FPGA and is compliant with IEEE802.3ae specification.

It is designed to be connected to a PCS/PMA IP with only one clock domain.

MAC TX Features

• Transmit data FIFO interface to define the payload data
• Transmit Status FIFO interface to define if the CRC has to be append or to transmit a Error Control character
• Transmit Pause interface to ask the MAC TX to transmit a Pause Frame
• Transmit FIFO RX Pause interface to ask the MAC TX to transmit a Pause Frame when FIFO RX becomes nearly full
• Transmit Configuration interface to define the Device Ethernet address, the padding and the Inter Frame Gap
• Transmit Statistics interface to collect the type of frame transmitted :
  • Frame byte sent
  • Frame done
  • Unicast Frame
  • Multicast Frame
  • Broadcast Frame
  • Control Frame
  • AOE Frame
  • Pause Frame
  • VLAN Frame
  • Stacked VLAN Frame
  • FIFO underrun
  • Frame with Error Control character
  • Frame Flushed because of a bad start of frame
