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.

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.
