New cable eases data-center crunch News & Analysis 9/28/2007 Post a comment Quellan Inc. and W.L. Gore & Associates have collaborated on a new copper interconnect for data center systems that the duo claims will significantly reduce power, size and latency while extending reach.
Wideband log detector delivers high dynamic range up to 10 GHz News & Analysis 9/28/2007 Post a comment Hittite Microwave Corporation has introduced its fourth logarithmic detector/controller product, which is ideal for RF power measurement and control in cellular/PCS/3G, WiMAX, WiBro, fixed wireless, radio link and radar applications over the full 1 MHz to 10 GHz frequency range.
IMEC sets new record for 9bit, 50 MSamples/s SAR ADC with a figure of merit of 65 fJ News & Analysis 9/28/2007 Post a comment An ultra-low power (0.7 mW), high-speed (50 MSamples/s) analog to digital converter (ADC), presented by IMEC at this year's ISSCC conference, achieves a figure of merit of 65 fJ per conversion step. This is 2.5 times better than the best ADC of this kind ever reported in research papers and an order of magnitude better than the best commercially available ADC IP blocks in 90nm CMOS.
Designing RF remote controls for DTV products Design How-To 9/26/2007 Post a comment In the short history of television remote control units, several different schemes have been tried. Early examples from the 1950s used wires, a single beam of light and ultrasonic sound to change channels and control the volume. These have obvious limitations. For instance, the photoelectric cells in the light beam example couldn't tell the difference between a flash light, an ordinary table lamp or even sunlight. This could lead to some chaotic television viewing.
Controller supplies power to CableCard hosts Product News 9/26/2007 Post a comment Designed to supply power to CableCard 2.0 cards in CableCard host systems, the MIC2569YQS from Micrel supports both S-Mode (Single Stream Video) and M-Mode (Multiple Stream Video) through a simple-to-control parallel interface.
Audio amp reduces EMI, optimizes power Product News 9/26/2007 Post a comment National Semiconductor says it has introduced the industry's first single-chip 3-W mono Class D audio amplifier with spread spectrum technology and an integrated boost converter. This device enables portable products to operate at a constant output power even at low battery voltages.
150-W power conversion IC speeds energy-efficiency compliance Product News 9/26/2007 Post a comment Power Integrations has announced the TOPSwitch-HX AC-DC power conversion chip, which incorporates a 700-V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
Electric motorbike teardown Teardown 9/26/2007 6 comments Vectrix designed its battery-powered VX1 motor scooter to go up against motorbikes from the likes of Honda and Yamaha. A teardown of the system shows how successful the company was at balancing performance with economy and low emissions.
Dual N-channel MOSFETs cut board space by 50% Product News 9/25/2007 Post a comment Fairchild Semiconductor's two latest dual N-channel PowerTrench MOSFETs are two highly integrated modules that are designed to reduce board space while providing the ability to achieve higher conversion efficiency in synchronous buck designs.
Bosch breaks ground for wafer fab News & Analysis 9/25/2007 1 comment Bosch has started construction works for its new wafer fab in Reutlingen, Germany. The production will be used predominantly in automotive electronics.
HD interface chipsets allow CE systems to connect wirelessly Product News 9/24/2007 Post a comment Check out these Wireless High-Definition Interface (WHDI) chipsets from Amimon, that make it possible for a wireless HD video connectivity net that allows consumer electronic devices to share HD content throughout the entire home, up to 30 meters (100 feet) through walls, while maintaining wire-equivalent quality with no latency.
Flextronics to close French plant Product News 9/24/2007 Post a comment Singapore-based electronic manufacturing services provider Flextronics International Ltd. plans to close its plant at Chateaudun, France, according to an Agence France Presse report.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
