Norwood, MA (02/06/2006) -
Sound clarity, image quality, battery life, download speed, form factor, and quality of service are just some of the attributes that wireless industry observers will be scrutinizing during the 3GSM World Congress in Barcelona, Spain February 13-16, 2006, and Analog Devices, Inc. (NYSE: ADI) will be on-hand to demonstrate the critical signal processing technologies that are improving the user experience along each of these dimensions. As a leading technology supplier to the cellular industry for more than 15 years, ADI’s wireless product portfolio spans a wide range of technologies from sensors, power management, audio amplifiers, complete chipsets and reference designs for cellular handsets, to digital signal processors (DSP), converters and radio frequency integrated circuits (RFICs) for cellular and WiMAX infrastructure. Many of these products will be demonstrated in ADI’s booth located at Hall 1, Stand D43.
“As the wireless industry expands from voice-centric communications to multimedia entertainment, our customers’ needs are increasingly aligned with our expertise,” said Jerald G. Fishman, Analog Devices’ president and CEO. “The high-performance signal processing challenge in wireless communications is intensifying, creating new opportunities for innovative analog and digital signal processing (DSP) technology.”
Leading the Industry with Dual-Mode TD-SCDMA/GSM Solutions
Cellular operators in China have verified dual-mode TD-SCDMA/GSM equipment based on ADI’s SoftFone® baseband chipset. ADI will demonstrate 3G products, including the SoftFone-LCR chipset supporting the Low Chip Rate (LCR) TD-SCDMA air interface, and SoftFone-W for W-CDMA handsets. Also on display will be the SoftFone AD6720, which integrates GSM/GPRS digital and analog baseband processing and power management functions in a single device.
Simplifying Quad-Band Radio Design
Leveraging ADI’s innovative closed-loop polar modulation technology to improve linearity and ease design complexity, the AD6546 Othello®-E transceiver integrates virtually all the necessary components for a complete quad-band EDGE radio design that is 30 percent smaller than competitive devices. The AD6541/6547 Othello-W transceiver for 3G W-CDMA and TD-SCDMA handsets will also be displayed.
Creating Exciting New User Interactions for Cellular Handsets
Mobile phones gain a new dimension of user interface by utilizing motion sensing and situational awareness to monitor where the handset is and how it is being used or controlled. Applications include menu navigation, gaming, and smart power management to extend battery life. The ADXL330 3-axis motion sensor requires a mere 200 microamps at a supply voltage of 2.0 V, and is priced to meet the requirements of the handset market.
Demonstrating touch control capabilities for mobile handsets, the AD7142 capacitance-to-digital converter (CDC) enables the design of contemporary touch controls that are paper-thin, yet highly reliable. The AD7142 can be programmed for a variety of sensor configurations, such as finger-driven scroll bars, 8-way position sensors, and scroll wheels that drive pop-up menus, making it easier to browse through large files of music, pictures and video.
Enabling Superior Image Quality
ADI’s AD5398 lens driver chip delivers high performance in a small package. The AD5398 is the smallest and most integrated digital-to-analog converter (DAC) solution for camera cell phones that offer a range of functionality, such as optical zoom, auto focus, and image stabilization. Featuring an ultra-small size of only 1.7 mm x 1.5 mm and up to 120 mA of drive at 10-bit resolution, the AD5398 does not require any other components for lens actuator control.
Extending Battery-Life in Next-Generation Camera Cell Phones
The ADP1652 white-LED flash controller and power management IC provides dc-dc conversion and timing control for white-LED camera flash units. It can drive one or two high-power LEDs with currents up to 500 mA, and includes an I2C control interface in a small 3 mm x 3 mm LFCSP package.
Broadening the Band with WiMAX
ADI will demonstrate an 802.16-2004 (WiMAX) system transferring a video stream between a base station and a WiMAX client device. The base station uses the TigerSHARC® Processor for the physical layer processing, as well as linear and mixed-signal components in the radio. Additional ADI products featured in the demo include the ADF4001 PLL synthesizer; the AD826 high-speed, low-power op amp; the AD8350 differential amplifier; the AD9862 dual digital programmable converter; and the ADL5500 RF power detector.
