Celadon Systems, Inc. announces its VersaTile probe cards with a -65°C to 300°C operating temperature range for low leakage measuring of off currents, and a way to increase test throughput during wafer level reliability tests such as HCI, NBTI, TDDB and BTS. The probe card features a rigid ceramic and metal chassis with integrated cable strain reliefs.
Real-Time Innovations (RTI) announces its RTI Recorder, a software system for logging the high-throughput data, events and messages that drive the behavior of distributed real-time applications. The recorded activity can be used for future analysis and debugging, regulatory compliance and replay for testing and simulation purposes.
The Wireless Telecom Group Co. announces its Noise Com J7000 jitter test system that alters serial signal streams through injection of Gaussian noise in a way that reflects real world signal behavior. To evaluate performance of components and systems, it is capable of adding specific amounts of white noise to the signal stream that allows the measurement of signal-to-noise ratio (SNR), carrier-to-noise ratio (CNR) and bit-error-rate (BER).
PCB Piezotronics introduced Model 482C54, a compact benchtop signal conditioner for ICP, IEPE and charge output piezoelectric sensors. The signal conditioner is compatible with accelerometers, microphones, pressure transducers, force sensors and strain sensors. It can accept a direct voltage input signal, allowing it to be used with most voltage sensor signals.
Uni-form epoxy preforms, manufactured by Multi-Seals, are available in a low cure-temperature epoxy called DC-202LT. DC-202LT will cure as fast as 5 minutes at 175°C (350°F) or at temperatures as low as 100°C (212°F) for 2 hours. This epoxy is suitable for sealing components that cannot withstand the cure temperatures of many heat-activated epoxies. The faster cure of the epoxy is also a benefit for large-scale sealing operations that require quicker cure schedules. Its preforms are one-part epoxy resins that are solid at room temperature. Close tolerances on preform configurations, consistent pre-mixed ratios of resin to catalyst
ON Semiconductor expanded its computing products portfolio with the introduction of three new power controllers, specifically designed to meet the efficiency requirements of notebook PCs. The NCP5371, NCP5218, and NCP5215 controllers address the notebook power subsystem needs for Vcore, DDR memory, and CPU chipsets respectively. According to the company, the controllers improve the efficiency of power management subsystems in notebook computers by up to 5 percent, thereby extending battery life.
Linear Technology introduced the LTC4090, an autonomous linear PowerPath manager, ideal diode controller and stand-alone high input voltage battery charger for portable USB devices. For high efficiency charging, the switching front-end topology accommodates various inputs, including high voltage power sources up to 38V (60V max withstand capability) such as 12V regulated/unregulated AC/DC wall adapters, FireWire ports or automotive power. In addition, the IC accepts low- voltage power sources such as 5V wall adapters
Analog Devices expandr its Blackfin line with the ADSP-BF52x family, a scalable series of processors for portable applications. Using the Dynamic Power Management capabilities of Blackfin to achieve power efficiency as low as 0.16 mW/MHz core power at 250 MHz, these processors offer system designers a wide choice with a high-performance/low-power series (ADSP-BF527/BF525/BF522) operating at 600 MHz, and an ultra-low-power series running at up to 400 MHz
ON Semiconductor unveiled an open ATX reference design that meets the new Energy Star requirements for ATX power supplies used in desktop PCs. The design offers efficiency that is said to exceed the Energy Star requirements under all specified load conditions, and it allows power supply manufacturers to bring highly efficient power supplies to market with readily available technology.
ON Semiconductor’s seventh GreenPoint reference design is for a 200W power adapter used to power game consoles -- allowing engineers to implement adapters that provide minimized active- and standby mode power consumption. The 200W adapter for game consoles has a dual output voltage, which makes the requirements for minimum active efficiency and maximum standby mode power more challenging to meet.
Semtech’s SC196 and SC196A 1.5A DC/DC step-down (buck) regulators feature high efficiency due to low quiescent current and power save modes to target the lower voltage levels needed for next-generation portable device designs. The SC196 uses external feedback to allow the output voltage to be set anywhere between 1V and the input voltage for design flexibility. The SC196A uses two programming pins to set the output voltage to 1V, 1.05V, 1.2V or 1.8V.
