New I/O Expansion Devices Support Multicast for Optimized Resource Utilization in Computing and Embedded Applications
December 8, 2008
SAN JOSE, Calif., December 8, 2008IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced two new PCI Express® (PCIe®) Gen2 switching solutions that extend the company’s product and technology leadership position. Optimized for computing and embedded applications, the new solutions are based on proven, robust IDT switching architecture and technology, and support multicast functionality for increased system resource utilization.
The two new devices are the latest members of the industry’s broadest PCIe Gen2 switching solution portfolio. The new solutions – a 32-lane, 8-port and a 48-lane, 12-port – also demonstrate the IDT corporate initiative to provide devices that are power efficient by incorporating advanced features to minimize power consumption, maximize performance-per-watt, and reduce total cost of ownership and thermal design complexity. Moreover, these new additions decrease time-to-market and reduce system validation testing by utilizing the proven IDT switch and interface technology employed in the existing family of IDT PCIe Gen2 switches.
Both new devices support PCIe multicast functionality, which allows any switch port to simultaneously send identical data to two or more switch ports, increasing system resource utilization by decreasing the previously required hardware and software overhead needed to send copies of data in a looped manner. This extension of the PCIe standard ensures consistency in data and table information among multiple system elements and extends the reach of PCIe into emerging enterprise computing and embedded applications requiring robust data coherency and sharing.
The IDT Gen2 PCIe switches are fully compliant with the PCI-SIG® PCIe base specification 2.0 and provide customers the option of doubling the throughput bandwidth of existing PCIe lanes to 5 gigabits per second of data transfer for cutting edge designs or allowing a 50 percent reduction in the number of PCIe lanes and board traces necessary to support link throughput requirements for a more cost effective design.
Each of the IDT PCIe switching solutions has a dedicated evaluation and development kit for device testing and analysis, and system emulation. Each kit consists of a hardware evaluation board with representative upstream and downstream connectivity, and an IDT-developed, GUI-based software environment that enables the designer to tune system and device configurations to meet system requirements. Moreover, to ensure that each OEM system design is optimized for production and meets its time to market objectives, IDT provides customers with extensive, collaborative technical support including system modeling and signal integrity analyses, and schematic and layout review services.
Packaging and Availability
