Ethernet

The RM674 is a PCI edge card designed to offer maximum 1000Mbit Ethernet connectivity. Using 1000BaseSX (LX option is available), the RM674 is capable of full duplex operation.

The RM674 Ethernet/PCI interface includes a powerful DMA engine with very deep FIFO buffers (64K byte). This assures continuous, full bandwidth operation with minimum PCI overhead. The RM674 has three options for I/O connectivity: LC, VF-45 or MT-RJ—each with SX or LX option. A mix of SX and LX is possible in any combination.

• PCI 64bit/66Mhz
• DMA engine
• Full 1000Mbit point to point performance
• Jumbo frame capable
• Four 1000Mbit Ethernet fiber ports
• Interchangeable, pluggable transceivers
• Connector options LC, VF-45 or MT-RJ
• 1000BaseSX (LX optional)

Host off-loading features

• Packet filtering based on checksum errors
• SNMP and RMON statistic counters
• Hardware TCP checksum off-loading
• Support for various address filtering modes:
  • 16 exact matches (unicast or multicast)
  • 4096-bit hash filter for multicast frames
  • Promiscuous unicast and promiscuous multicast transfer modes

Low cost, effective interconnect

Two RM674 boards can be directly cabled with a simple "cross-over." This configuration creates a full duplex 1000Mbit dedicated data path (for each port)—delivering high bandwidth at very low cost. More complex, dedicated interconnects can be created using a hub or switch. Both point-to-point and switched hubs, in full duplex mode, remove many determinism concerns raised with traditional Ethernet solutions. This makes the RM674 an excellent candidate for high performance interconnects that require real-time determinism.
