SUMIT™ Expansion Modules

VersaLogic Corp. (Eugene, OR) has developed two expansion modules that feature the Stackable Unified Module Interconnect Technology (SUMITTM) interface scheme. These PC/104-sized modules are suitable for systems that need a small (3.65" × 3.8") footprint. Expansion boards may be added, including PCI Express (PCIe) lanes, USB ports, LPC, SPI, and SMB. For legacy applications, the accessory cards are also equipped with a PC/104 ISA feed-through connector.

EBX-Sized Single Board Computer

The EBC-Z8510-G single board computer (SBC) from WinSystems (Arlington, TX) is powered by an Intel 1.1GHz AtomTM processor. It measures 203mm × 147mm and supports the SUMIT-ISM I/O expansion standard plus COMIT (Computer On Module Interconnect TechnologyTM). The interface features two Gigabit Ethernet ports, CRT and LVDS flat panel video, a MiniPCIe card interface for a wireless networking module, four USB 2.0 ports, four serial COM ports, HD audio, PATA controller for both a CompactFlash and hard disk, 48 lines of digital I/O, LPT, and a PS/2 port for keyboard and mouse. Additional I/O module expansion is supported with two SUMIT and legacy PC/104 connectors. This RoHS-compliant board operates over a temperature range of -40 to +70°C.

Designing the Next Generation of Military Robots

Many recent blockbuster films and best-selling books depict the robotic apocalypse and have shed a negative light on military robotics. However, not all unmanned system development is aimed toward building autonomous machines that spy on foreign nations or neutralize enemy threats. The United States Department of Defense (DoD) continues to aggressively invest in developing unmanned systems and technologies because robots can perform the tasks that are too dull, dirty, or dangerous to warrant warfighter intervention.

USB-to-Synchronous Cable Enables IP Data Communications for Tactical Radios

Warfighters can benefit greatly from having radio IP-based data communications at the theater level. Unfortunately, the vast majority of the 750,000 tactical radio systems currently in use do not have the necessary built-in hardware and software to send IP-based data communications. The installed base of tactical radios is comprised of various makes and models that are not interoperable, further making it difficult to achieve theater-level data communications.

Improved Interference Rejection Using Multi-Static Radar Signal Processing

In multi-static radar (MSR), the transmit/ receive aperture is divided into a number of sub-apertures that can be placed in various locations relative to each other. These locations can be chosen to optimize the performance of the radar in terms of some specific task. Two multi-static approaches have been investigated:

Analysis of On-Chip Heat Distribution in the Design of RF Power Detectors and Transistor Arrays

The simulation of electromagnetic (EM) and thermal properties of semiconductor and substrate materials has been demonstrated to be particularly helpful in the optimization of the design of Monolithic Micro wave Integrated Circuit (MMIC) power amplifier (PA) modules. Various design challenges, however, have to be dealt with in specific ways, and may require efficient approaches that accommodate reasonable approximations in the development and troubleshooting phases. EM and heat transfer analysis at the semiconductor device structure level allows building accurate models for simulation tools.

Clock Oscillator

Crystek Crystals (Fort Myers, FL) has released the CCSO- 014-1090, a 1.090-GHz surface acoustic wave (SAW) clock oscillator that produces low-noise, low-jitter performance with true SineWave output, and -138 dBc/Hz phase noise at 10 kHz offset. It comes in a 14 PIN DIP hermetically sealed package, features a 12V input voltage, and generates a true sinewave with +12 dBm minimum output power. It has no sub-harmonic, and the second harmonic is -40 dBc max. Operating temperature is -55 °C to 105 °C.
