Connect to Ethernet with integrated tri-mode Ethernet MAC blocks

Virtex™-5 LXT, SXT, and FXT platform FPGAs include 2-8 embedded tri-mode Ethernet media access controller (MAC) blocks. The integrated functionality reduces total system cost by:

• Reducing design and verification effort
• Freeing approximately 1,800 logic cells per Ethernet MAC in the FPGA fabric
• Reducing component count
• Simplifying system design with pre-verified UNH compliant embedded blocks

Features at a Glance

• Tri-mode Ethernet MAC - 10/100/1000 Mbps modes of operation
• IEEE 802.3 compliant
• UNH-interoperability tested and certified
• Programmable PHY Interface
• MII/GMII with SelectIO™ interface
• SGMII when used with RocketIO™ transceivers (requires external phy)
• Real-time statistics interface ports for performance monitoring of both Tx and Rx Frames
• Jumbo frames support
• Receive address filter to accept/reject packets
• DCR-bus connection to microprocessors
• Complete single-chip solution for 1000 Base-X when using RocketIO transceivers (no external phy required)
• Ideal for network management or remote FPGA monitoring
