IDT has developed a new family of central packet switches (CPS) that address the interconnect needs of embedded applications that utilise DSPs, FPGAs or processors.

The CPS family enables much flexibility, specifically 4x and 1x port options coupled with enhanced features for system bring-up and debug. The family includes three device configurations - with 16-port (80KSW0002), 12-port (80KSW0004), and 8-port (80KSW0003) options for 1x port counts. Each port can be configured for 3, 125 Gbps, 2,5 Gbps or 1,25 Gbps, for long haul (backplane) or short haul (board) transmission profiles, with configurable drive strengths and pre-emphasis settings. Moreover, the CPS family is pin-to-pin compatible with the IDT PPS Gen 2 family of devices, allowing customers the flexibility to upgrade their next-generation systems to the more powerful pre-processing solution with no impact on hardware or board design.

The devices are configurable through any of the Serial RapidIO, JTAG, or I²C ports. They include a loopback mode which gives users the added flexibility to work with the physical layer of the IDT device and quickly identify the source of any performance bottlenecks. They also incorporate useful diagnostics with '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, designed in conjunction with Texas Instruments, together with a comprehensive range of software development tools, such as GUI, API, drivers and third party tools. A handy calculator allows users to calculate power usage in various usage profiles, allowing designers to adjust device options to achieve maximum power savings. Each kit supports all other IDT pre-processing solutions and sRIO-enabled solutions such as the 10G Serial Buffer. IDT also provides customers with extensive collaborative support, including system modelling and signal integrity analyses, and schematic and layout review services.
