Molex offers the new PCI Express* revision 2 specs connectors in a through hole configuration for high-bandwidth workstation and server applications. PCI Express is a third generation I/O architecture. PCI-SIG* recently revised the PCI Express specifications from version 1.1 to version 2.0. This revision doubles the PCI Express interconnect bit rate from 2.5 GT/s (gigatransfer per second) to 5 GT/s per lane. Unlike the previous version in which the PCI bus was implemented via multi- drop parallel architecture, the PCI Express incorporates a point-to-point signaling using differential pairs. A 16-lane link now could provide approximately 16Gbps of data-transfer. With this increase in signaling speed, the PCI Express now provides better support to high-bandwidth applications. It is also backward compatible with current PCI Express 1.1 version products.

Molex's through hole connector version of the PCI Express version 2.0 specs provides customers design flexibility for a narrower interconnect links. This would improve data-transfer at a lower cost.

All Molex PCI Express connectors are compliant with PCI-SIG* specifications. For more information on these specifications please see www.pcisig.com
