Signal processing challenges answered at
3GSM
Sound clarity, image quality, battery life, download speed, form factor and quality of service will all be addressed by Analog Devices at 3GSM in Barcelona.
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 scrutinising during the 3GSM World Congress in Barcelona, Spain, 13th to 16th February 2006, and Analog Devices 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), convertors and radio frequency integrated circuits (RFICs) for cellular and WiMAX infrastructure

DSP needs no ASICs to run software basestations
Analog Devices has unveiled a new DSP equipped with Layer 1 software that together are claimed to reduce system costs of 3G infrastructure equipment by up to 50%.
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 analogue baseband processing and power management functions in a single device.
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% smaller than competitive devices.
The AD6541/6547 Othello-W transceiver for 3G W-CDMA and TD-SCDMA handsets will also be displayed.
Mobile phones gain a new dimension of user interface by utilising 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 three-axis motion sensor requires a mere 200uA at a supply voltage of 2.0V, and is priced to meet the requirements of the handset market.
Demonstrating touch control capabilities for mobile handsets, the AD7142 capacitance-to-digital convertor (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, eight-way position sensors, and scroll wheels that drive pop-up menus, making it easier to browse through large files of music, pictures and video.
ADI's AD5398 lens driver chip delivers high performance in a small package.
The AD5398 is the smallest and most integrated digital-to-analogue convertor (DAC) solution for camera cellphones that offer a range of functionality, such as optical zoom, auto focus, and image stabilisation.
Featuring an ultra-small size of only 1.7 x 1.5mm and up to 120mA of drive at 10bit resolution, the AD5398 does not require any other components for lens actuator control.
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 500mA, and includes an I2C control interface in a small 3 x 3mm LFCSP package.
ADI will demonstrate an 802.16-2004 (WiMAX) system transferring a video stream between a basestation and a WiMAX client device.
The basestation 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 synthesiser; the AD826 high-speed, low-power op amp; the AD8350 differential amplifier; the AD9862 dual digital programmable convertor; and the ADL5500 RF power detector.
