Circuit Design Tool

Sunstone Circuits, Mulino, OR, announced DFMplus, a Design to Manufacturing tool that allows potential issues to be fixed in the PCB design phase. The tool helps users verify PCB designs before ordering. The tool features a preview of possible failure points, provides efficient transfer of design file data into manufacturing, and enables designers to submit partial designs, or regions of the design, as a section-by-section check.

Data Acquisition Board

Measurement Computing (Norton, MA) offers the USB-2020 high-speed, two-channel data acquisition board that provides simultaneous sampling at rates up to 20 MS/s per channel. Users can sample data from both channels at an overall rate of 40 MS/s to the 64-megasample onboard memory, or continuously stream data to a host computer at up to 8 MS/s for one or both channels over a high-speed USB connection. Each channel has its own A/D converter for simultaneous sampling to eliminate channel skew and ensure that phase information between channels is maintained.

Oscilloscope

The LabMaster 10-100Zi 100-GHz oscilloscope from Teledyne LeCroy (Chestnut Ridge, NY) achieves 100 GHz and 240 GS/s. The 100-GHz technology is designed for engineers working on communication systems, high-bandwidth electrical components, and scientific research. The modular and flexible platform allows users to build oscilloscopes with high channel counts, even when only one or two channels are in the base model. The oscilloscopes are built from a single Master Control Module (MCM-Zi) that contains the display, control, and ChannelSync clock distribution architecture, managed by a server-class CPU.

Data Acquisition Card

Innovative Integration (Simi Valley, CA) introduced Atropos, an XMC I/O module with low-noise clock generation and distribution for data acquisition and communications timing applications. The module has four output clocks and four output triggers, as well as a clock/reference input and a trigger input. Multiple cards can be cascaded to synthesize dozens of phase-synchronous, ultra-low-jitter clocks and triggers within radar, beam steering, and MIMO applications. In the sample clock generation mode, the card can generate clocks from 74.06 to 3080 MHz. All clock outputs may be referenced to an on-card 280-ppb temperature-compensated oscillator, or an external clock input. In distribution mode, a supplied clock and trigger are buffered and distributed 1:4. The PLL circuit is fully programmable. Example code supports control of all card features. Software tools for host development include C++ libraries, and drivers for Windows and Linux.

Automotive Circuit Protection Using High-Reliability TVS Diodes

Diode technology eliminates transient surges and enhances vehicle safety. Littelfuse, Chicago, Illinois Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards. The three major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming these transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.

A Resistive, High-Voltage, Differential Input Interface in a 3.3-V BiCMOS 0.5-μm Process for Extreme Environments

NASA’s Jet Propulsion Laboratory, Pasadena, California Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.
