Switchtec PCIe switches to support extended industrial temperatures

Microsemi has announced the availability of its Switchtec(TM) PFX-I Gen3 PCIe switches with support for extended industrial temperature range. The new PM857x PFX-I PCIe switches support the feature set of Microsemi's PFX PCIe fanout switches, and are designed to operate in harsher environments demanded by applications including automation, defense, healthcare and industrial computing.

The Switchtec PFX-I extended industrial temperature PCIe Gen3 switch family has passed thermal cycle testing, interval testing at various extreme temperatures and vigorous temperature humidity testing of several hundred hours to ensure durability at different humidity levels and wide temperature ranges. Thus, the switches operate over an extended temperature range of -40 degrees C ambient to 105 degrees C junction, supporting up to 48 ports, 48 Non-Transparent Bridges (NTBs), 24 virtual switches, advanced error handling, hot- and surprise-plug controllers, dynamic port bifurcation and dynamic partitioning.

"With the PFX-I family, Microsemi is expanding our addressable application space for Switchtec PCIe switches into new markets including industrial, security and defense," said Pete Hazen, vice president and general manager of the data center division at Microsemi. "The extended industrial temperature support enables use of our Switchtec family of PCIe switches in an even broader set of applications that include harsh environmental requirements."

Microsemi's new PFX-I device is ideally suited for a variety of industrial and defense applications, such as medical imaging, instrumentation, security and radars. According to market research firm IndustryARC, the radar semiconductor market will grow from $433 million in 2017 to $505 million in 2022. The firm expects the equipment market for other industrial applications to continue expanding as well during this forecast period, with medical imaging anticipated to grow from $21.8 billion to $25.5 billion, instrumentation to expand from $1.07 billion to $2.34 billion and video surveillance to grow from $23 billion to $35.9 billion.

Microsemi's Switchtec PM857x PFX-I family comprises switches from 96 lanes to 24 lanes, providing:

  • Flexible port bifurcation, from x2, x4, x8, x16 lanes per port;

  • High port density, NTB density, and switch partition density;

  • Advanced error containment and hot- and surprise-plug support to prevent system crashes;

  • Advanced diagnostics and debug features to identify, diagnose and fix problems; and

  • Separate Refclk Independent SSC (SRIS) for cabled PCIe and lower cost system designs.

Microsemi's Switchtec PM857x PFX-I extended industrial Gen3 PCIe switches are now in production and available to order.

CPU choice for display based systems
Behind every display based system is the CPU which acts as the brain of the entire module creating the data that is presented as well as driving the I/O peripherals, display and touchscreen. There are many factors to consider when choosing the right CPU for your project, including whether you pick a complete Single Board Computer (SBC) or a stripped back core module (COM).
