10/100/1000 Mbps MAC

The 10/100/1000 Mbps MAC is a flow control capable Media Access Controller (MAC) for Ethernet which operates at 10-Mbps, 100-Mbps or 1000-Mbps. In half duplex mode the controller implements the IEEE 802.3ab Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. In full duplex mode, the controller implements the IEEE 802.3ab MAC Control Layer and the PAUSE Operation for flow control. The controller is capable of identifying receipt of VLAN tagged frames.

FEATURES

  • Fully compliant with IEEE 802.3ab
  • Can operate at either speed 10/100/1000Mbps
  • GMII interface employed for 1Gbps
  • MII interface employed for 10/100Mbps
  • Can work at both half and full duplex mode
  • Can send PAUSE frame for flow control in full duplex mode
  • Back-off in CSMA/CD mode (half duplex)
  • Support frame burst in 1000Mbps mode
  • Back pressure algorithm in half duplex mode
  • FCS checker for bad frame filter
  • MDIO interface for status exchange with upper layer controller
  • SPI interface for management
