PCIe Gen 2 switches

18 March 2009 Telecoms, Datacoms, Wireless, IoT

IDT has developed two new PCI Express (PCIe) Gen 2 switching solutions optimised for computing and embedded applications.

The two new devices – a 32 lane, 8 port and a 48 lane, 12 port – support PCIe multicast functionality, which allows any switch port to simultaneously send identical data to two or more switch ports, increasing system resource utilisation 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 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 Gbps data transfer for cutting-edge designs or allowing a 50% reduction in the number of lanes and board traces necessary to support link throughput requirements for a more cost effective design.

Each of the switching solutions has a dedicated evaluation and development kit for device testing and analysis, and system emulation. IDT also provides customers with extensive, collaborative technical support including system modelling and signal integrity analyses, and schematic and layout review services.
