Serial RapidIO central packet switches

8 July 2009 Telecoms, Datacoms, Wireless, IoT

IDT has announced a new member of its family of central packet switches (CPS). The new device provides designers with a mix of port count, performance and power consumption for up to six 4-ports of 10G connectivity. The device offers sustained throughput for the full range of minimum and maximum packet sizes while providing power consumption low enough to eliminate the need for an additional heat-sink device in many applications. Moreover, the Serial RapidIO (S-RIO)-based switch addresses the interconnect needs of embedded applications whose functionality is central to routing packets for distribution amongst DSPs, FPGAs or processors, other switches, or any other S-RIO-based devices.

As with other members of the CPS family, the 80KSW0006 incorporates in-house fourth-generation SerDes and S-RIO core switch technology to provide enhanced signal integrity, flexibility and scalability. The new device supports S-RIO packet switching (including unicast, multicast and optional broadcast) from any of its six input ports to any of its six output ports and is pin-to-pin compatible with the existing IDT PPS family of devices, allowing customers the flexibility to upgrade their systems to the powerful pre-processing solution with no impact on hardware or board design.

Leveraging the Serial RapidIO, JTAG and I²C interconnect standards, the CPS family specifically addresses such markets as wireless and wireline, imaging, medical, military, IPTV and other high-end communications markets and embedded applications. Supporting software solutions provided for the CPS and PPS switch families include an IDT-developed power calculator that allows customers to estimate power usage in various usage profiles. Customers can use this calculator to adjust device options to achieve maximum power savings.

The devices include a 'loopback mode', which gives customers the flexibility to work with the physical layer of the IDT device and quickly identify the source of any performance bottlenecks. Additional functions provide 'kill' and 'trace/mirror' capabilities that enable an added layer of security that is often critical in embedded applications.

The CPS solutions are supported by ATCA- and MicroTCA-compatible, dedicated development platforms together with a range of software development tools, such as GUI, API, drivers and third-party tools.
