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.

Boards PCIe downstream and PCIe Upstream connected togetherPCI 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.
