Networking card provides high data throughput

Concurrent Technologies has launched its latest networking PMC mezzanine card - the CL PMC/GB3, a two channel Gigabit Ethernet adapter with 1000Base-T and 10Base-T/100Base-Tx capabilities.

Concurrent Technologies has announced the latest addition to its range of networking PMC mezzanine cards - the CL PMC/GB3, a two channel Gigabit Ethernet adapter with 1000Base-T and 10Base-T/100Base-Tx capabilities.

The adapter's +5V power usage is typically 5W with dual Gigabit operation and it is targeted at applications that require high data throughput and low latency.

The CL PMC/GB3 provides high speed networking through the Intel 82546GB Gigabit Ethernet controller, providing individual MAC and frame controllers supporting 64Kbyte Tx/Rx FIFO ports, along with IP, TCP and UDP checksum off-loading.

This controller allows the board to automatically negotiate transfer rates of 10, 100 or 1000 Mbits per second in full or half duplex mode.

Supporting IEEE 802.3ab, IEEE 802.3 and IEEE 802.3u, the adapter's physical connection to an Ethernet network is via industry standard RJ45 connectors that allow connection to low cost CAT5 UTP cabling.

The CL PMC/GB3 is a single-size card and is compliant with the Common Mezzanine Card (CMC) specification.

The adapter complies with the PCI specification, features 3.3 or 5Volt signalling and 32bit or 64bit transfers, can operate at 33 or 66MHz and has bus master capability.

The adapter does not require an onboard PCI bridge as the Intel 82546GB is a dual channel Gigabit Ethernet controller that connects straight to the host board's PCI bus.

A 512Kbyte BIOS EPROM is supported in a 32-pin PLCC JEDEC socket and includes PXE firmware.

This board can be used with Concurrent Technologies' CompactPCI, VME, Multibus II, or with any other PMC compliant host board.

Operating systems supported include Windows XP, Windows XP Embedded, Windows 2000, Windows NT, Linux, VxWorks and QNX.
