QPIXEL
Full HD H.264 codecs feature low power
eeProductCenter's Ismini Scouras says: "Qpixel Technology has added high definition (HD) devices--QL303 and QL305--to its low-power, H.264 codec family. The QL303 and QL305 provide a broad H.264 feature set by supporting baseline, main, and high profiles of the H.264 standard for resolutions ranging from QVGA (320x240) to full HD (1920x1080). Qpixel offers full HD H.264 encoding at less than 275-mW of power, confirming its commitment to Green Technology initiatives for lowering energy consumption in consumer electronic devices."

Readers say:

"The price is very high for what they are offering which is mostly standard available features... this is a $12 technology max"

"Ahead of the pack. The market may not yet be ready for implementation."

ANALOG DEVICES
Digital isolation chips save board space, reduce costs
eeProductCenter's Gina Roos says: "Analog Devices, Inc. (ADI) has expanded its family of digital isolation products with a series of four-channel devices that isolate both data and power. Each device integrates ADI's iCoupler digital isolation technology and proprietary isoPower dc-to-dc converter, providing both isolated power and isolated signal channels within a single package."

Readers say:

"Simple, elegant solution to solve problem common in industrial or other reliability requirements."

"The peak-to-peak Jitter is not specified. According to Pulse Width Distortion it is very high. Not intended to use for analog parts isolation like ADCs and DACs. Most likely will be good for digital isolation."

In case you were wondering, here's how Ultimate Products works: Our editors select up to 10 of the most significant products posted at www.eeProductCenter.com during the calendar quarter. Then, using an electronic balloting process, we submit the products with the accompanying editorial reviews to selected, qualified readers. Those readers score the products by technical significance and
USABILITY on a scale of 1 through 5, with 5 being the highest score. The product ranked No. 1 in each category was judged as most technically significant for that category. Relative
USABILITY rankings and selected reader comments are also reported. More than 1,000 of you helped to choose these products. As always, we are grateful for your enthusiastic participation.
