The PCIe-8398 host interface card communicates over a fully transparent PCI Express Gen 3 x16 link to either the single-port PXIe-8398 or dual-port PXIe-8399 remote control module to offer up to 13.7 GB/s of sustained data throughput. Engineers can use the second port on the PXIe- 8399 to daisy chain additional chassis, making it possible to directly interface multiple PXI Express chassis to a single host computer, whether it is a desktop or rack-mount PC. The PXIe-8394 bus extension module supports peer-to- peerstreamingupto6.8GB/sbetweenchassis-separated instruments with PCI Express Gen 3 connectivity such as the second-generation vector signal transceiver. In addition to multichassis systems, the PXIe-8394 allows high-throughput communication with peripheral devices like RAID data storage arrays or theATCA-3671 FPGA Module for ATCA. These peripherals typically operate with substantial data sets and can benefit from utilizing the latest PCI Express interfaces. This new family of PXI remote control and bus extension modules complements the already-released PXIe- 8880 embedded controller and PXIe-1085 24 GB/s chassis, both of which also feature PCI Express Gen 3 connectivity. This high-bandwidth portfolio of chassis and controllers is an important part of the NI ecosystem that engineers can use to build smarter test systems. These test systems benefit from more than 600 PXI products ranging from DC to mmWave and feature high-throughput data movement using PCI Express bus interfaces and sub-nanosecond synchronization with integrated timing and triggering. Supported by a vibrant ecosystem of partners, add-on IP and applications engineers, the NI platform helps dramatically lower the cost of test, reduce time to market and future-proof testers for tomorrow’s challenging requirements. Read this white paper to learn more about how NI’s PCI Express Gen 3 chassis and controller offerings help engineers build smarter test and measurement systems.

Surface-Mount Intelligent Low-Power Modules from STMicroelectronics Save Space in Energy-Efficient Motor Drives STMicroelectronics has added five space-saving surface-mount intelligent power modules (IPM) to its SLLIMM™-nano family, giving the choice of IGBT or MOSFET outputs for in-motor or other space- constrained drives all the way from very low power ratings up to 100W. The new modules deliver high conduction and switching efficiency, especially in hard-switching circuits at frequencies up to 20kHz. The integrated gate-driver circuitry is engineered to minimize electromagnetic emissions (EMI) by managing switching voltage and current slopes (dV/dt, di/dt). The thermally efficient package enhances reliability and allows heatsink-free design, while 2.7mm creepage and 2.0mm clearance ensure safety isolation within the compact dual-inline SMD footprint. The module pin configuration is optimized to simplify circuit-board layout. Awide range of domestic and industrial appliances, such as small fans, roller shutters, refrigerator compressors, dishwashers, draining and recirculation pumps, and general low-power motor drives, can benefit from the small size, high energy efficiency, excellent reliability, and safe, low-noise performance of ST’s new IPMs. Extra features integrated alongside the gate driver and 500V MOSFET or 600V IGBT/freewheel-diode array include an uncommitted operational amplifier and a comparator that let designers implement advanced current sensing and over-current protection with minimal external components. Smart shutdown with high-speed fault detection, interlocking, and under-voltage lockout are all built-in, and integrated bootstrap diodes simplify powering the module’s gate-control circuitry. The new SLLIMM -nano power modules, comprising the STIPNS1M50T-H, STIPNS2M50T-H, STIPNS2M50-H, STGIPNS3H60T-H, and STGIPNS3HD60-H, provide a choice of 1A, 2A, or 3A current rating (at 25°C). All are packaged as NSDIP-26L fully-molded dual-inline surface-mount devices. Engineering samples are available now and volume production will commence in Q4 2017. Pricing starts at $5 for 1000 pieces of the STIPNS1M50T-H.
