 "External PCI Express Cabling Spec Released")
PCI-SIG, the Special Interest Group responsible for PCI Express industry-standard I/O technology, today announced the availability of the PCI Express External Cabling 1.0 specification, which extends the PCI Express interconnect architecture “outside the box.”
Standard cables and connectors have been defined for x1, x4, x8, and x16 link widths. Sideband signaling is provided via the cable to attain compatibility with existing silicon and software; this leverages existing software and infrastructure, provides ease-of-use and helps accelerate adoption of the technology.
“This specification helps the industry create new products that will take PCIe technology out of the box — enabling PCIe solutions for IO expansion drawers, external graphics processors, tethered mobile docking, communications equipment and embedded applications,” said Al Yanes, PCI-SIG chairman and president. “With the large market PCI Express has achieved since its introduction in 2002, this is a great opportunity for OEMs to take products to new levels with PCIe technology.”
The new cabling specification currently supports signaling rates of 2.5GT/s. In the future, PCI-SIG expects to continue to advance the cabling technology by providing new enhancements and foresees support for 5.0GT/s signaling rates.
