Readability and organisation: it may sound simplistic, but those are the main requirements in a website according to you, the readers of Electronicstalk, in response to our request for feedback. (I guess we're taking relevance of content as read!)
Under the "readability" category, various sites were praised for "clear typography" (and not just by those who criticised other sites for over-small text) and "clear use of English", which is reassuring for those of us who try to retain certain standards.
And under "organisation" many sites were praised for "intuitive navigation" and speed of searching.
So, having disqualified Electronicstalk itself - which naturally polled several times the votes of its nearest rival - the most praised website for the Electronicstalk community was dear old Google. Not only did you like its presentation and ease of use, it was also praised for "almost always" coming up with the goods.
(This is something for which many PC users will be thankful. The next time you get a blue screen of death, try putting the error message into a search on www.google.com.)
I hope you find this issue of our weekly newsletter useful. We now have more than 8000 engineers and other industry professionals on the circulation, so you're in good company. In addition to the new products, news and ideas featured here, there are hundreds more on our website and dozens more being added daily, so do take a look if you can.
But you don't need web access! All the full stories behind the summaries and headlines in this newsletter can be retrieved by email alone: see details below. In the meantime, if you've got any suggestions as to how we might make the site or the newsletter better, email me directly.
Best wishes

OUR TOP TEN NEW PRODUCTS SELECTION
=======================================================
1. System controllers put cores to efficient use
MIPS Technologies has a new system controller family that complements the high performance of MIPS processor cores, enabling SoC designers to increase overall system performance for next-generation applications and accelerate SoC development. SOC-it system controllers have already been licensed to several customers, including NEC and leading providers of networking, satellite communications and set-top box solutions. The SOC-it system controller family is one more step in MIPS Technologies' strategy to offer system platforms that enable customers to get to market faster with higher performance system-level products.

2. Kit aids DSP-based video development
Texas Instruments has released a network video developers kit (NVDK) for the TMS320C6000 digital signal processor platform. The new kit gives manufacturers of advanced video applications, such as video infrastructure and networked video appliances, the key hardware and software elements needed to accelerate their development time of leading-edge digital video solutions. The NVDK brings together the benefits and capabilities of TI's first-generation application developers kits for imaging and networking on a second-generation C64x DSP development platform.

The new microprocessor from Hitachi incorporates an SH-3 32bit SuperH RISC CPU core, a 32-byte cache memory and comprehensive on-chip peripheral functions including USB. The SH7705 will enable the implementation of high-performance, low-power-consumption digital home appliances, portable information devices, and office appliances such as fax machines and colour printers. Sample shipments begin in August 2002.

4. High attenuation from soft gaskets
The latest soft gaskets from EMI shielding specialist, TBA Electro Conductive Products deliver attenuation in excess of 100dB across a wide frequency range for applications requiring the highest performance. The ECP 400 soft EMI shielding gaskets comprise a conductive fabric bonded over a soft nonwicking thermoplastic elastomer (TPE) closed cell foam. The gaskets are ideal for shielding applications where high performance levels over a wide frequency range are required and particularly where low closure forces combine with a requirement for good environmental sealing.

5. Package design tool gains time-saving functions
Zuken has added two new time-saving enhancements to its Package Predictor advanced packaging solution for designers developing single- or multichip IC packages. Both offer early-stage insights into critical tradeoffs in package layout and assembly. The package re-use function allows engineers to determine whether an existing package design is practical, rather than having to develop a new package for each new die.

7. Multifunction card features versatile triggering
The PXI-2010 is a four-channel simultaneous 2Msample/s A/D and two-channel 1Msample/s D/A multifunction card from Adlink Technology. The PXI-2000 series combines the advantages of CompactPCI's ruggedised Eurocard architecture and VXI's intrachassis signalling to create a flexible and cost effective multifunction card for the instrumentation market. The PXI-2010 uses the latest carrier and daughter modular design concept, which separates the analogue circuitry and digital circuitry into two cards, thus it greatly reduces the signal noise generated by digital parts and increases the effective numbers of bits (ENOB) in data measurement.

8. Diamond heat spreaders dissipate more than copper
Diamonex CVD diamond heat spreaders from Morgan Advanced Ceramics are ideal for high power device applications, such as laser diodes, microwave FETs and MMICs, and advanced multichip modules (MCMs). Due to diamond's extremely high thermal conductivity, Diamonex CVD diamond heat spreaders improve performance by reducing junction temperatures, allowing for increased power output, speed, and reliability.

10. More sensitivity for current sensor
Allegro MicroSystems has developed a novel design of current sensor based on a precision linear Hall-effect integrated circuit coupled with a magnetic circuit optimised to maximise device sensitivity. The entire assembly is housed in a new package configuration for easy mounting and implementation in automotive or industrial applications. The combination of a precisely controlled self-aligning assembly process (patents pending) and the factory-programmed precision of the Hall sensor results in a high degree of product uniformity and exceptional performance, particularly for sensing high currents.
