University officials said a public memorial service is being planned for later this semester on the Berkeley campus. Information regarding the service will soon be posted on a university Web site.

A standardized set of recommended deliverables would also help. That doesn't mean every IC vendor would provide exactly the same set of models and documentation; rather, the vendor would provide a checklist of items that the pc board designer could inquire about. A common taxonomy would ensure that everyone was talking about the same thing.

It would be great if every IC or FPGA came in a nice, clean package with controlled impedance lines for every signal. That's not a cost-effective solution, of course.

But at the very least, designers should know what they're getting and have some chance of determining whether a device will work on their board before they commit to it.

The Art of Design column offers opinions and perspectives on the technology, techniques and business of electronics design. It covers design automation, test, packaging, boards and silicon. Suggestions or comments may be sent to rgoering@cmp.com.

Manhasset, N.Y. — After launching 17 high-speed converters in 2004, Analog Devices Inc. will kick off the new year with two of its highest-performing devices to date. The first is a 14-bit, 80-Msample/s analog-to-digital converter with a 5- to 7-dB improvement in spurious-free dynamic range (SFDR); the second is a 16-bit, 1-Gsample/s digital-to-analog converter with power consumption of 1 watt. Both target such applications as wireless infrastructure, broadband wireless and communications test equipment.

Aside from low power and high ac performance in terms of SFDR and intermodulation distortion, both converters were designed with high integration in mind, said John Hall, marketing manager for the high-performance A/D line at Analog Devices (Norwood, Mass.). All converter processing is done on-chip,” he said, and an SPI interface has been provided for control and test.”

In the case of the monolithic AD9444 pipeline A/D, high integration translates to on-chip decimation filters and track-and-hold circuitry, with no external reference or driver components needed. However, it's the SFDR figure of 97 dBc and the signal-to-noise ratio of 73.1 dB, both at 70-MHz input, that has Hall particularly excited.

Optrex TFT LCD modules equipped with Natural Color Matrix technology include an 8.4-inch XGA module (P/N T-51639D084J-FW-A-AB), a 10.4-inch SVGA module (P/N T-51944D104J-FW-A-AA), a 12.1-inch SVGA module (P/N T-51866D121J-FW-A-A), and three 15-inch XGA modules (P/N T-51863D150J-FW-A-AA, T-51863D150J-FW-A-AB and T-51863D150J-FW-A-AD).

The company also notes that the new TFT LCDs with NCM, while offering critical performance enhancements, will not come with a significant increase in price as compared to standard non-NCM versions. Suitable applications include point-of-sale displays in markets such as fast food and retail, gaming applications, test and measurement instrumentation, diagnostic and imaging equipment, and automotive interior displays.

Additional details on NCM are provided in a new technical paper, Natural Color Matrix: Delivering Color Fidelity”, available at Optrex's web site.

Pricing for Optrex LCDs with Natural Color Matrix technology starts at $258.40 for theT-51866D121J-FW-A-AA 12.1-inch SVGA module in OEM quantities.
