Concurrent Unveils XM 510/x24 Quad Port Gigabit Ethernet XMC Adaptor

Concurrent Technologies announces a family of networking XMC mezzanine cards – the XM 510/x24, a quad port Gigabit Ethernet adaptor supporting 1000Base-T, 100Base-Tx and 10Base-T. Where performance, functionality and space are key elements, the XM 510/x24 provides four network ports in a single-width XMC site on a suitable host board, e.g. CompactPCI®, VXS, VPX or VME. Commercial and extended temperature versions are available and ruggedized, conduction-cooled or air-cooled, versions will be available shortly. The board is designed for applications that require high-speed data throughput and lower-latency communications, such as image transfer, industrial control, telecommunications, defence and a variety of embedded markets applications.

Concurrent XM 510/x24 Quad Port Gigabit Ethernet XMC AdaptorThe XM 510/x24 contains two Intel 82575EB Ethernet Controllers. Each controller implements two Ethernet ports and integrates (into a single device) the functionality of two Ethernet Media Access Controllers (MAC), two 10/100/1000Mbits/s PHY transceivers and a x4 PCI Express interface. The XMC host board’s connection to the XM 510/x24′s two Ethernet controllers is via a x4 PCI Express switch. The four Ethernet ports can either connect to the front or to the rear panel.

Each MAC and LAN controller provides the Host Offloading and MAC functionality for its link. The Host Offloading includes transmit and receive IP, TCP, and UDP checksum offloading, TCP segmentation and VLAN support. The MAC Controller provides IEEE 802.3x flow control, 8Kbyte Transmit and Receive FIFOs to support jumbo frames and a 48Kbyte per-port packet buffer. Each PHY provides the physical layer functionality for its link and contains the transmitters and receivers for full and half duplex operation at 10Base-T, 100Base-Tx and 1000Base-T operation. Also provided is IEEE 802.3ab auto-negotiation, auto MDI/MDI-X selection and polarity correction. Internal loop-back is available for self-diagnostic purposes.

The XM 510/x24 is a single-size card and is compliant with the XMC (Switched Mezzanine Card) specification. Each Ethernet Controller connects to its own 128 Kbytes in-circuit programmable Flash EPROM that includes PXE firmware.

For ease of integration the XM 510/x24 supports many of today’s leading operating systems, including Linux®, Windows® XP, Windows® XP Embedded, Windows® 2000, LynxOS®, QNX®, and VxWorks®.
