Low-ohmic analog switches improve audio performance News & Analysis 1/12/2004 Post a comment Parameters of low Ohmic analog switches such as On resistance, charge injection and On resistance flatness have already been discussed in recent publications. But less information has been published on choosing proper low Ohmic switches for specific applications. In this article, a Fairchild engineer analyzes audio signal distortion to fully understand the trade-offs between power savings and signal fidelity in ultra portable designs.
Automotive controller drives down parts count Product News 1/10/2004 Post a comment The IR3220S from International Rectifier is a highly integrated H-bridge motor controller IC for automotive DC applications up to 6 amps. It's specifically designed to drive motors and actuators, including fuel, water and vacuum pumps, compressors, throttle controls, power seats and door locks, window lifters, automatic sun roofs and windshield wipers. It cuts component count by as much as 90 percent over discrete solutions.
System-level chips add power to portables Product News 1/9/2004 Post a comment FOCUS ON MANAGING POWER - With users demanding more from their portable and wireless devices, power-managing ICs are advancing toward more sophisticated system-level solutions. A snapshot of the most recent chips, which are largely DC/DC converters with expanded functionality to serve six or seven major power-managing areas, shows intense activity in battery chargers, and a flurry of LED drivers and audio amps.
High-Speed Backplanes Pose New Challenges to Comms Designers News & Analysis 1/7/2004 Post a comment High-Speed Backplanes Pose New Challenges to Comms Designers
As backplane speeds move beyond 3 Gbit/s, designers will encounter problems not seen at lower rates. Fortunately, through the use of modeling techniques, designers can tackle these issues head on. A Rambus engineer shows how.
Decoder among the first to support WMV9 based DVD players Product News 1/7/2004 Post a comment Sigma Designs announced the EM8620L, the next generation series of media processors that support Windows Media Video 9 (WMV9), the advanced video compression technology The chip also supports HighMAT (High Performance Media Access Technology) that enables better performance and navigation of personal audio, video and photo CDs in next generation entertainment devices.
Making the Most Out of 802.3af News & Analysis 1/7/2004 Post a comment New power-over-Ethernet specification allows designers to remove the power cord and powerup over Ethernet lines. An article borrowed from CommsDesign.com offers analog-friendly insights into this new IEEE spec.
Controller makes power supply redundancy easy News & Analysis 1/5/2004 Post a comment Traditional methods for connecting redundant power supplies usually involve placing a diode in series with each power supply output and tying either the cathodes or anodes, depending on whether the power supply is positive or negative, together at the load. This is commonly referred to as diode OR-ing and, although simple, is far from an ideal solution. In this article (intended for EE Times' InFocus section on backplane power management), a TI engineer offers a more efficient means of coupling
Coax chipset enables home net backbones News & Analysis 1/5/2004 Post a comment chip set from startup Entropic Communications lets end users turn their coaxial connections into a backbone network in the home. Wireless connections-mostly wireless-LAN links-are quickly becoming the de facto approach for distributing broadband connections and multimedia content from a router to a node, such as a laptop. But Wi-Fi systems struggle to penetrate some walls and thus fall short in providing total coverage in a home. That coverage issue will loom larger as end users start to distri
IC market to exceed SIA's 2003 forecast News & Analysis 1/5/2004 Post a comment The Semiconductor Industry Association (SIA) said it expects global chip sales to exceed its 15.8- percent growth forecast for 2003 compared to the previous year. At the same time, worldwide sales of semiconductors rose to $16.13 billion in November 2003, a 4.5 percent increase from the $15.43 billion recorded in October. The total also represented a 25.7 percent rise from November 2002, SIA reported Monday (Jan. 5).
