STMicroelectronics (NYSE: STM), a world leader in analog and mixed-signal ICs, has announced the first six devices in a series of clock-distribution ICs, which are the first in the market to provide per-channel output-enable controls for precision clock management in embedded and handheld applications.

The two-channel STCD1020, three-channel STCD1030, and four-channel STCD1040 save component count, board complexity and bill-of-materials costs in multi-mode devices such as cellular handsets and M2M (machine-to-machine) communications. By distributing a single master clock to multiple clock domains, designers can eliminate multiple individual-crystal clock sources for chipsets supporting GSM, Bluetooth, WLAN, WiMAX or other RF communications, and also set-top boxes. With fewer crystal components, these applications also benefit from greater physical ruggedness.

The individual output-enable controls combine with a fast startup time, as well as 2.6mA typical quiescent current and 1 microamp standby current for the STCD1040, to minimize power consumption in battery-powered and embedded applications. From receipt of an Enable signal, the selected channel’s output is stabilized within 50 microseconds from standby. The power savings deliver advantages such as longer battery life, easier thermal management and smaller physical size. The STCD1040 draws 30% less current than a discrete 4-channel solution, which requires five individual emitter-follower circuits and typically occupies over 60% more PCB area. High channel isolation also ensures low crosstalk, which can be difficult to achieve with discrete components. In addition, low phase noise directly enhances signal quality.

Designed for transmission of a single-ended sine-wave or square-wave in the range 10MHz to 52MHz, these clock-distribution ICs also integrate an AC coupling capacitor to further minimize external components. They are capable of driving loads up to 20pF to simplify output circuitry. The standard supply voltage is 2.5V to 3.6V, while the option of 1.65V-2.75V operation allows use with low-voltage peripherals. The specified operating temperature range of –40 degrees C to +85 degrees C allows use in a wide variety of commercial and industrial applications.

The devices’ small TDFN packages deliver additional space savings, with the STCD1020 offered in a 2 x 2mm 8-lead package, the STCD1030 in a 2 x 2.5mm 10-lead package, and the STCD1040 in a 2 x 3mm 12-lead package. The STCD1040 is priced at $0.80 in quantities of 10,000 pieces.

Lumex announces the launch of two new high-power LED technologies, TitanBrite™ and SuperBeam™ that provide bright, intense light with low power consumption.

TitanBrite is a 5-watt LED that delivers light intensity of up to 250 lumens of brilliant white light at 700mA of current. Compatible with most surface mount processes, TitanBrite LEDs are ideal for use in spot lighting applications including display lighting, sign/graphic backlighting, medical device usage, emergency indication, architectural and decorative lighting, high-end appliances, or for any application that calls for high intensity point source lighting.

SuperBeam, the first high-power 1-watt LED technology to be offered in through-hole design in the North American market, is designed to focus intense light into a narrow beam. The through-hole design is well-suited for applications like flashlights that do not adopt surface mount configurations. SuperBeam is ideal for applications requiring small spotlighting such as a flashlight beam in a retail showcase, smaller medical device applications, or any application that calls for bright illumination with a narrow focused beam.

“The TitanBrite and SuperBeam LED technologies further expand Lumex’s comprehensive family of high-powered LED products,” explained Richard Halliday, Director of Sales and Marketing at Lumex. “Lumex’s ability to deliver industry-leading technical support to help companies integrate these technologies in a way that closely matches their human interface goals further sets these products apart.”

TitanBrite LEDs are available in cold, warm and neutral white for enhanced product differentiation. Cold white colors project brightness and cleanliness while warm white shades project a more natural and ‘soft’ looking light.

TitanBrite LEDs are 10mm x 10mm in size with domed lenses and are RoHS compliant. Production quantities are available in 8 - 10 weeks. Pricing is dependent on color specified and quantity ordered, and is approximately $10 per unit in 10K quantities.

SuperBeam LEDs provide an optical efficiency of 35 lumens per watt with a tight beam angle of 25 degrees. This 10mm package is available in cold, warm and neutral white as well as in red, yellow, blue and green for product differentiation opportunities. Production quantities are available in 8-10 weeks. Pricing is dependent on color and quantity ordered and is approximately $2 per unit for 10K quantities.

Building on its leadership in power management and energy-efficient products, National Semiconductor Corp. (NYSE:NSM) today announced that it has entered the photovoltaic market with new technology designed to increase the overall energy output of solar electric power generating systems. National’s SolarMagic™ technology extracts the maximum power efficiency of each photovoltaic panel, even when some panels in the array are compromised by shading, debris or inherent panel-to-panel mismatch.

Today’s solar installations are disproportionately impacted by non-uniformities, caused by shading, panel mismatches or dirt accumulation. For example, a small amount of shading in the array can cut the energy harvest of a system in half. This significantly limits the energy output, design and location of typical residential solar installations. Shading conditions can even invalidate local utility and governmental incentives, making certain installations cost-prohibitive. National’s SolarMagic technology recoups up to 50 percent of the lost energy thereby minimizing the economic impact of shading and other real-world conditions.

“National’s entry into the photovoltaic market is a natural extension of our focus on energy efficient systems,” said Brian L. Halla, National’s chairman and CEO. “Our technologists solved this real-world problem and are enabling consumers to produce more energy under adverse conditions and reduce the payback time of their investment with an environmentally friendly source of power.”

SolarMagic technology is a per-panel electronics solution that maximizes power output of multi-panel installations. It is compatible with today’s solar architectures regardless of the underlying solar cell technology.

National has entered field trials with its SolarMagic technology. REgrid Power, Inc., one of the largest solar installers in California, has begun system testing of National’s SolarMagic technology.

“We are impressed with National’s SolarMagic technology in our field trials and have seen a significant performance improvement in our solar installation,” said Tom McCalmont, president and chief executive officer of REgrid Power, Inc. and founder and executive chairman of SolarTech, a Silicon Valley consortium. “We have observed energy output improvements of up to 44 percent during shaded conditions and 12 percent overall versus the same system running without SolarMagic technology.”

Several additional solar companies are slated to join the field trials over the next several months, and National will expand field trials to include installers in other countries with high adoption rates of solar. Later this year, National plans to introduce SolarMagic products for solar installers and system providers to include in their installations.
