PCIe Cabled DownStream board, up to 230Mbytes/sec. Fpga System and DMA Driver

Cyclone4GX PCIe DownStream

This product allows to extending the host PCI Express bus through a high-speed cable. Using a PCIe compliant cable, the PCI Express bus can be extended up to seven meters from the host CPU.

PCI Express on cable is the first architecture supporting high-end embedded applications, it is a PCI and PCIe compatible expansion and extension cable. PCI Express officially abbreviated as PCIe, is a computer expansion standard card  designed to replace the older PCI, PCI-X, and AGP standards.  PCI Express standard has been developed by PCI-SIG group.

Transmitting the host bus over copper cables opens a new world in the embedded design area. The PCIe cabling solution allows a system configuration having a high-end computing core in a cooled area that is hosting an embedded and remote I/O subsystems, with different thermal environment. The host and I/O system may have different form factors, specifically suited for the environmental or performance requirements of each sub-system. For example, a high-end, dual Intel Xeon class host system provides the user with the computing power for an and a high-speed data link to a high-end embedded I/O subsystem based on MicroTCA, PC/104, 3U CompactPCI Express, or proprietary form factor.
