PCI Express® takes the best features and ideas behind PCI and combines them with more than 10 years of industry “lessons learned.” The result is a robust, scalable, flexible, cost-effective I/O interconnect that will serve the industry for the next 10-15 years.

Key Features

• PCI Express architecture is an industry standard high-performance, generalpurpose serial I/O interconnect designed for use in enterprise, desktop, mobile, communications and embedded platforms. Device B Device PCI Express®
• It is PCI-compatible by using the established PCI software programming models. PCI Express facilitates a smooth transition to new hardware and allows software to evolve and leverage the advantages of PCI Express features.
• Gen I has a scalable bandwidth of 16 Gigabytes-per-second at its initial signaling rate of 2.5GHz. In the future, Gen II promises much higher transfer rates using higher frequency signaling technologies.
• Supports multiple interconnect widths via 1, 2, 4, 8, 12, 16 and 32 lane configurations aggregated to match application bandwidth needs.
• Serves new and innovative, hot-plug/ hot-swap add-in card and module devices.
• Delivers unique, advanced features such as Power Management, Quality of Service and other native functions not available in other I/O architectures.
