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
Mesh networks gather steam with standards

1/5/2004   Post a comment
Many organizations recognize the value that a wireless mesh network can provide, but are unsure whether they should implement one that is managed or ad hoc. The decision revolves around how to implement an authentic network without wires: one that is scalable, secure, managed and architected for performance. The need for mesh networking and its many inherent advantages has led to a call for standards in ad hoc networks that should solve many of the outstanding issues.
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

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).

Control failure by sensing the heat
Product News  
1/1/2004   Post a comment
Controlling the amount of heat produced or dissipated by today's more powerful electronic equipment becomes critical as the real estate shrinks enabling heat related problems to occur more easily. It can be a tricky challenge to resolve but several companies are offering possible solutions.

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.
