TI's two analog-to-digital converters aren't typical in any way. They are very high-resolution, 24-bit delta-sigma converters that cover just about every requirement for high-resolution de-signs. These two products provide data rates that can meet high-speed requirements and support the data rate to decrease the noise for low-speed requirements. Chipcenter's Paul O'Shea has this assessment.

Selecting PLLs for ASIC Applications requires tradeoffs
News & Analysis  
9/25/2003   Post a comment
PLLs, like many other analog IP macros, come with many features and specifications. Selecting the correct PLL early in the design can help the design team make tradeoffs when they are less costly, improve the integration quality of the PLL, and avoid surprises close to tapeout. From the September PA magazine folio, a True Circuits expert gives this assessment of what you should look for.
Broadcom enters analog, OpenCable tuner markets
News & Analysis  
9/23/2003   Post a comment
Broadcom Corp. (Irvine, Calif.) significantly widened their address to the market for set-top box and TV electronics today with the introduction of an analog cable tuner. The company has a couple of years experience with tuners designed for QAM cable systems (where a good QAM system may require -82 dBC phase noise and -52 dBC distortion), but the requirements for the CableLabs Open Cable specification are considerably more stringent. Ron Wilson has this report.

Getting 12-bits of Resolution out of your 10-bit A/D - Part 2: Oversampling
News & Analysis  
9/10/2003   Post a comment
In Part 1, Arrow's Bob Fugerer discussed increasing an A/D's resolution for near DC signals. In Part 2, he considers and oversampling example: Monitoring a 60Hz sine-wave with better than 70db of dynamic range, or 12-bit resolution. The minimum sampling rate is set at 500Hz since there is information at 120Hz and 180Hz that could also be of interest. To do this, we need to develop a new moving average for the effective number of bits (ENOB) that includes both signal bandwidth and oversampling.
Programmable Logic Devices offer co processor muscle for high bandwidth image processing " Part 1
News & Analysis  
9/10/2003   Post a comment
In medical imaging applications, such as Computed Tomography and Magnetic Resonance Imaging, the input data is not a stream of successive bytes, but rather it is a large data block (an image) residing in memory or on disk. The task of the image processing chain is typically to tile the image into sub-blocks, perform a series of linear algebraic transforms on those blocks, and place the resultant data back on the disk. In this two-part series, an Altera engineers offers insights on using programm
