PCI Express switches optimised for I/O connectivity

8 August 2007 Computer/Embedded Technology

IDT has announced that its low power PCI Express (PCIe) switches - optimised specifically for I/O connectivity applications - have been added to the PCI Special Interest Group (SIG) PCI Express Integrators List. The eight devices have passed PCIe specification 1.1 compliance testing.

The IDT family of switches was designed to meet the I/O connectivity needs of second and third generation PCIe-based server designs, offering a competitive combination of power, performance per watt and package size. These characteristics are also essential to emerging applications in the communications, embedded and consumer markets, where PCI Express adoption is rapidly increasing. The I/O connectivity devices deploy a broad range of lane/port configurations, providing customers with flexibility in their choice of system architecture. They deliver a bandwidth ranging from 24 GBps for the 48-lane/12-port switch to 4 GBps for the 8-lane/5-port switch. They achieve this maximum throughput via their support of large payloads of up to 2048 bytes, and support of significantly more flow control credits than have been common in previous generations of switches.
