Can you invent a better smiley? Programmable Logic DesignLine Blog 9/27/2007 Post a comment Following my earlier blog on "The 25th Anniversary of the Smiley", one reader suggested a rather clever new design, which set me to wondering...
SerDes: A new definition? Blog 9/26/2007 Post a comment The mission of engineers is to find a better way and that might be what Align Engineering has done with its Align Lock Loop (ALL) technology.
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.
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.
FPGAs look for a lingua franca Signal Processing DesignLine Blog 9/26/2007 Post a comment ESL tools have made FPGA design a lot easier, but the lack of a common design language means the learning curve is still too steep.
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.
Implementing solid security on a Bluetooth product Design How-To 9/25/2007 Post a comment The first section of this article outlines the security features of individual Bluetooth components, and the subsequent section drills-down into the application component explaining the various types of Bluetooth security breaches and recommended solutions to thwart them from the product application.
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.
