Optocouplers maintain data integrity near high voltage noise News & Analysis 7/29/2003 Post a comment Factories have noisy environments that can make transmitting data over long distances a nightmare ---- unless the noise can be eliminated at the receiver. High-speed optocouplers that can handle data rates of up to 15 Mbits/s can isolate high frequency signals typically found in the factory data transmission. A Fairchild apps engineer offers provide background information on optocouplers and some applications circuits.

AmberWave gets credit from GE Technology Finance News & Analysis 7/22/2003 Post a comment AmberWave Systems Corp., a supplier of strained silicon technology, said Tuesday (July 22, 2003) that GE Technology Finance, a unit of the GE Structured Finance, has recently expanded its existing line of credit to AmberWave.
Overcoming 1394 asynchronous bandwidth limitations for consumer electronics devices News & Analysis 7/21/2003 Post a comment When adding IEEE 1394 to CE devices, system design engineers need to be aware that the bus bandwidth is shared among all devices on the bus, writes TI apps engineers. With isochronous traffic, there are few bandwidth issues since the bandwidth is guaranteed, but asynchronous bandwidth is not guaranteed, they say. System designers must pay close attention to factors that affect asynchronous bandwidth when designing their systems.
A marriage of design and test environments speed RF device characterization News & Analysis 7/9/2003 Post a comment Many companies are forging links between design and test - using measurement data to hone the accuracy of simulation models, and simulation results to tune test suites and procedures. An alliance between Ansoft and National Instruments promises to speed characterization and modeling procedures for RF devices. This piece (originally intended for this week's EE Times InFocus section on RF test issues) offers an overview.
Fab utilization above 90% by year-end, says Gartner News & Analysis 7/9/2003 Post a comment The semiconductor industry's utilization of wafer fab capacity should move back above 90 percent for the first time in three years in the first quarter of 2004 and remain there throughout the year, according to a forecast from market research firm Gartner Inc.

(UMC) was NT$7028 million (about $204 million) up 4.7 percent from the same month a year before and down 4.5 percent from sales revenue in May 2003, UMC said Wednesday (July 9, 2003).
Gartner quantifies back-end led 2003 spending revival News & Analysis 7/8/2003 Post a comment Market research company Gartner Inc. is forecasting 2003 to be a growth year in capital expenditure with equipment for packaging and assembly scoring a 26 percent rise over 2002 and wafer fabrication equipment scoring a more modest 9 percent growth.
Second-order IIR Filters will support cascade implementations - 5 Part digital audio application tutorial Design How-To 7/1/2003 3 comments It is possible to implement IIR filters of any order by cascading first- and second-order IIR sections. Today, as digital audio processors embodying this topology becomes commonplace in the market, the designer's challenge is to find a way to design coefficients for these to accomplish the overall filtering goal. This multi-part article series - by the knowledgeable and prolific Rusty Allred - brings together the basic information needed to design and implement a wide variety of audio filters. P
DC signal conditioning aids microcontroller readings News & Analysis 7/1/2003 Post a comment Certain types of low-level DC signals can present a challenge when trying to digitize using the internal analog-to-digital Converter (A/D) commonly found on many microcontrollers. These A/Ds typically have limited operating range and reference selection, which forces designers to condition the signal prior to digitization. A Cypress apps engineer offers some insights for boosting low-level signals.
