Power PLCC-4 LEDs offer more colors Product News 2/29/2008 Post a comment Avago has added four new colors -- cool white, warm white, blue and green -- to its family of super half-watt power PLCC-4 surface-mount LEDs for automotive and electronic sign applications.
LCD backlighting using 2-D LED dimming boosts TV performance and saves power Design How-To 2/29/2008 Post a comment Advanced backlighting technology using LED-based light sources and segmented control can create a vibrant viewing experience, while also reducing power consumption in LCD TVs. But adaptive backlight dimming requires a significant amount of image processing to be performed on the video stream to derive optimum backlight and pixel drive signals.
ARM tools add support for DaVinci and OMAP35x Product News 2/27/2008 Post a comment The ARM RealView family of development tools will provide enhanced support for the Texas Instruments DaVinci and OMAP35x platforms, including the recently-released DaVinci TMS320DM355 digital media processor and OMAP35x processors.
Exceeding the standard for wireless sensor networks Design How-To 2/26/2008 1 comment ZigBee claims to be "Wireless Control That Simply Works" and is optimized for low power operation and cost. But ZigBee is just one solution for wireless sensor networking applications and others can be easier-to-implement, more compact and use less power.
Sidedbar: Comparing ANT and ZigBee Design How-To 2/26/2008 Post a comment When designing a wireless sensor network, the decision between standard-based and proprietary solutions is not always an easy one. Here's one assessment of the pros and cons.
High def DVD Blog 2/25/2008 Post a comment Too bad this was just a format war, in which big bucks -- and perhaps a few careers -- but no lives were at stake. Speaking of bucks, Sony reportedly paid Warner Bros. some $400 million to get the exclusive Blu-ray release of their new films -- this was what ultimately tipped the tables.
Power management chip combines three DC/DC converters Product News 2/25/2008 Post a comment Targeted at portable devices with rapidly evolving feature sets, AnalogicTech is offering a pair of 3-channel devices that allow designers to combine three step-down DC/DC converters without radically altering their existing core system design or adding numerous discrete devices.
Infineon enhances power semiconductor portfolio Product News 2/25/2008 Post a comment At the Applied Power Electronics Conference (APEC), Infineon Technologies announced that it has added three new families of power semiconductors to its extensive OptiMOS 3 N-channel MOSFET portfolio. The devices enable designers to increase power density significantly, the vendor claims.
Silicon carbide ready for prime time Product News 2/25/2008 2 comments NASA thinks silicon carbide is ready to replace silicon in circuitry that must withstand ultrahot temperatures--as high as 1,000 degrees F--or deliver ultrahigh power.
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.
