Harsh Environment Instrumentation & Secure Microelectronics

Crossfield Technology is skilled at integrating emerging and existing microelectronics and interconnect technologies to create new products and implement cost effective solutions in the areas of secure microelectronics and instrumentation. Our scientists and engineers span the boundary between basic research and product engineering.

Innovation at Crossfield means discovering a radical new way to solve an old problem or to apply existing technology to address a new opportunity. The innovation may encompass a new algorithm, a novel microelectronics technique, a high-speed network, embedded software, or an ultra-low-power wireless sensor. All of the techniques are examples of technologies that can dramatically impact the size, performance, power consumption and mobility of a product.

Crossfield's network instrumentation provides innovative solutions to sensor data acquisition and hardware-in-the-loop (HWIL) simulation. Our instrumentation products integrate modular transducer interfaces with a broad range of wireless and wired network architectures to support a wide variety of applications. These products include low-speed wireless network interfaces such as IEEE 802.15.4, Bluetooth Low Energy (BTLE), IEEE 802.11 (WiFi), and ultra-high-speed wired networks including USB, 1/10/40 Gbps Ethernet and 40/56 Gbps InfiniBand and beyond.

Crossfield develops wireless and low-speed wired instrumentation platforms for harsh environment sensor data acquisition. These platforms capture the output of strain, temperature, acceleration, pressure, and other types sensors through a precision analog-to-digital converter and store the data in non-volatile memory. The data is either logged or transmitted in real-time to a remote location for further analysis. In the Ethernet based platforms, Crossfield supports Power-over-Ethernet such that data transfer, precision timing, and power are all transmitted down a single cable. Also, Crossfield recently developed an IEEE 802.15.4a RFIC that provides a standard IEEE 802.15.4 interface across a ultrawideband (UWB) physical layer. All of these instrumentation platforms can be controlled through National Instruments LabVIEW.

Crossfield provides novel communication architectures for heterogeneous high performance computing (HPC) clusters with hardware-in-the-loop. Our patented Multipath RDMA technology provides greatly increased bandwidth between computing nodes within HPC clusters while our high-speed network instrumentation provides high bandwidth data transfer into and out of clusters. The HPC systems and network instrumentation use Real-Time Operating Systems (RTOS), IEEE 1588 Precision Time Protocol (PTP), and the Open Fabrics Enterprise Distribution (OFED) to support precision event scheduling and synchronization along with a standardized software development platform throughout the entire system.
