3M's Twin Axial Cable
Twin Axial Cable from 3M is a flat, foldable and longitudinally shielded high-performance twin axial ribbon cable. 3M SL8800 Series Cable is for high data-rate applications that can make sharp turns and fold with little or no impact on electrical performance. The first products in this new family are for serial digital signaling over differential pair for high-speed internal cabling applications. Initially available in 4-channel 100 ohm 30AWG versions, two layers of SL8800 cable are less than half the thickness of an equivalent bundle of conventional twinax cable. Its construction allows the cable to fit through narrow openings and free up space in tightly packed systems or even enable design of new smaller form factors/architectures. The ribbon structure is integral to the cable. The structure also allows folding to occur without disturbing the pairs or compromising the performance.
3M cable is thinner, more routable, space-efficient and easier to terminate. The cable is less than 1 mm thick compared to up to 8 mm for competitive cables. It can be easily bent and folded in multiple places without affecting the cable's performance or longevity unlike most competitive products. The cable can be bent around corners or threaded between components, allowing it to avoid obstructing air flow or to open up valuable system real estate. 3M cable's built-in wire-to-board registration eliminates tedious wire handling, enabling consistent and reliable terminations. This is useful for automation in the assembly process.
Analog Devices' AD9467
The AD9467 is a 16-bit, monolithic, IF sampling ADC and is optimized for high performance over wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation and test equipment that require a high dynamic range. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. The AD9467 operates on 35 percent less power at 25 percent higher sampling rate than any other 16-bit data converter, providing a new level of signal processing performance for applications where high resolution over a wide bandwidth is needed.

The device's SFDR of 90 dBFS up to 300 MHz analog input and 60-femtosecond rms (root mean square) jitter helps lower the signal chain bill of materials and component count by allowing engineers to increase system performance at higher intermediate frequencies, thereby reducing the number of signal down-conversion stages.
Aptina's MT9H004 Image Sensor
Aptina's new high-performance APS-C format 16MP MT9H004 image sensor delivers maximum signal-to-noise ratio across all scene lighting and ISO speed conditions. Other MT9H004 features include 16MP still image capture at 10fps, live-view video support and 1080p/30fps HD video recording. A 5dB increase in SNR, approximately equivalent to gaining two full f-stops of range for the camera lens aperture, is achievable under low-light conditions without sacrificing performance in high-light environments, where it can achieve a 47dB max SNR. Through the addition of a pixel-level, dual-conversion gain (DCG) switch, Aptina DR-Pix technology combines two modes of operation in one pixel design - a low conversion gain (LCG) mode for large charge handling capacity in bright scenes, and a high conversion gain (HCG) mode with increased sensitivity and low read noise for low-light scenes. The DCG switch controls the switching on and off of a capacitor connected to the FD node. When imaging in high-light conditions, the DCG switch is turned on, utilizing the FD node's large capacitance to enable the LCG mode to handle large amounts of signal charge. In low-light conditions, the DCG signal is turned off, allowing the HCG mode to be used as an extra analog gain inside the pixel. Lower FD capacitance results in much higher conversion gain, higher sensitivity and reduced read noise. DR-Pix technology offers benefits for automotive imaging systems, surveillance and PC cameras that must often capture video in dimly lit conditions.

LeCroy Corp.'s SPARQ
The SPARQ is a new class of instrument; the Signal Integrity Network Analyzer. The SPARQ uses TDR/TDT to measure 40 GHz S-parameters and time domain responses on up to 4-ports at a fraction of the cost of a vector network analyzer with single button press operation. With its low price and automatic internal calibration capability, SPARQ eliminates VNA frustration and brings high bandwidth multi-port S-parameter measurements to a much wider audience. With the SPARQ's automatic calibration, S-parameters can be measured in minutes without any need to connect and disconnect calibration standards. This approach eliminates the frustration VNA users have with error-prone manual calibration procedures and expensive "ECAL" modules. In addition to S-parameter results, SPARQ calculates step and impulse responses and rho and Z profiles normalized to a user's rise time. All measurements can be made in both single-ended and mixed-mode configurations. Results are "simulation ready," using passivity, reciprocity and causality enforcements and results include a dc point, something that cannot be done with a VNA. All of these features are standard.
The SPARQ utilizes a high-bandwidth switch matrix to route signals from the TDR pulser/sampler and TDT sampler to the internal calkit and to the DUT. This architecture is cost-effective, and provides single-button-press operation. The reference plane is moved to the DUT via an algorithm that de-embeds the switch matrix and other external components such as cables. The SPARQ uses LeCroy's "CIS" timebase to acquire waveforms about 20x faster than other TDR solutions. The benefit is faster averaging, without linearity issues. Additionally, a wavelet denoising algorithm further eliminates noise, yielding the highest dynamic range of any TDR/T-based network analyzer (50db). SPARQ is designed specifically for the signal integrity engineering marketplace, for characterization and compliance testing of passive devices such as backplanes, interconnects, PC boards and cables.

WaveMasterA(R) 8 Zi-A digital oscilloscopes provide up to 45 GHz of bandwidth and 120 GS/s of sample rate combined with 768 Megapoints of analysis memory. 20 GHz bandwidth is available on each of the four channels; useful for testing emerging 40/100 GbE DWDM devices and systems. The WaveMaster 8 Zi-A is a single hardware platform with nine models from 4 to 45 GHz of bandwidth. This means engineers can stay current with emerging high-speed technologies by upgrading to additional bandwidth as needs change. The bandwidth of the WaveMaster 8 Zi-A is useful for leading-edge research and development applications, especially high-speed next-generation, long-haul optical network development. In addition to the 45 GHz capability, the oscilloscope may also be operated in a 30 GHz/2-channel or a 20 GHz/4-channel mode. This gives flexibility to utilize multiple channels at 30 or 20 GHz for timing validation while retaining the ability to utilize fewer channels for higher bandwidth signal fidelity measurements. The 20 GHz four channel rating of the 845Zi-A has 25 percent more bandwidth compared to competitive offerings.
The WaveMaster 8Zi-A models utilize second-generation silicon germanium (SiGe) components with none of the thermal conductivity, reliability, yield, cost and other concerns that captive in-house processes must contend with. LeCroy's 30 to 45 GHz 8Zi-A models make use of sixth generation Digital Bandwidth Interleave (DBI) to extend bandwidth without the deleterious effects of bandwidth "boosting". X-Stream II technology enables high throughput of data - even when the oscilloscope is analyzing 768 Mpt waveforms, by using variable waveform segment lengths to improve CPU cache memory efficiency.
Mentor Graphics' Tessent YieldInsight Software
Mentor Graphics' Tessent YieldInsight software analyzes large populations of scan diagnosis reports to intelligently and quickly identify the most likely yield loss mechanisms in digital semiconductor devices. The software leverages data collected during production tests and implements sophisticated statistical testing techniques to automatically identify hidden yield limiters and prioritize yield enhancement efforts.
- Automatic identification of hidden yield limiters.
- Visualization of results consistent with yield analysis practices in wafer maps, signature Paretos, physical heat maps and layout viewers.
- Drill-down capability to effectively pick die for failure analysis.
- Analysis automation and ability to integrate with other systems.
The Tessent YieldInsight software product is specialized for understanding and identifying semiconductor yield loss from production scan test data. Augmenting traditional methods, this solution reduces the time to root cause by 75 to 90 percent. Tessent YieldInsight customers have been able to accelerate their cycle time to root cause from months to days, reduce the amount of wasted PFA and uncover previously hidden yield limiters representing the last 1 to 2 percent in high-volume manufacturing. Tessent YieldInsight provides the right questions to ask to select the right devices for PFA that represent the systematic yield loss mechanisms. While the software visualizes results consistent with yield analysis practices, it also automatically identifies systematic defects and includes drill-down capability to effectively pick die for PFA. The solution leverages layout-aware diagnosis that provides a rich and detailed data set for each failing device. The statistical analysis is designed especially to work on this dataset. At advanced process nodes, it's increasingly difficult to separate random and systematic defects, often resulting in wasted PFA and slower yield ramp.

MP Antenna Ltd.'s Trident-2.4GHz Multi-Polarized Wi-Fi Antenna
The Trident-2.4GHz Multi-Polarized Wi-Fi antenna allows for quick and easy retrofit of most standard "rubber duck-" style antennas often found in wireless network deployments. The technology behind the Trident has improved connectivity in difficult non-line of sight applications typically found in industrial and warehouse applications. Tests have shown that even in areas with satisfactory connectivity, the Trident increases signal capture, reducing data loss and packet retries. The net effect is faster throughput and better utilization of bandwidth. Because of its ability to capture any available signal, use of the Trident saves money on wireless network deployments because fewer access points are required. Video streaming improves with reduced pixilation and increased resolution. The Trident also extends range and resolution when deployed in robotic video surveillance systems. The Trident can even extend battery life by reducing the amount of time a radio operates in high power mode searching for a signal.
Its patented multi-polarized technology enables it to transmit and receive signals in all polarizations. The 3-D design also incorporates built-in spatial diversity. This feature virtually eliminates multipath cancellation by emulating the performance of complex multiple radio and antenna systems oriented in different spatial locations. The Trident creates a broad full signal pattern free of voids so common with standard omni directional antennas.
