Dual-mode 3G TD-SCDMA/GSM operation has been achieved on Analog Devices' SoftFone-LCR chipset.
"This design-in demonstrates Analog Devices' expertise in signal processing, in this case applied to advanced wireless devices", said Vincent Roche, Vice President, Sales and Marketing, Analog Devices.
"Sharp's expertise in colour display and camera technology combined with our analogue and mixed-signal technology results in an excellent product that should be very popular in the GSM world".
"We selected Analog Devices' chips because they offer the performance we need", said Dr Stephen E Bold, Managing Director, Sharp Telecommunications of Europe.
"The flexibility of the SoftFone architecture, for example, allows us to interface our camera and 64K-colour LCD display easily by adding our own software, thus avoiding the need to develop customized hardware.
In addition, ADI enables low power consumption allowing us to achieve 250 hours of standby time".
Camera phones represent one of the fastest-growing segments of the cell-phone market.
Already popular in Japan, the first camera phones are just beginning to emerge for use on the networks used in North American and European markets.
According to a recent report by Strategy Analytics entitled "Strategic perspectives on cellular camera phones", 16 million camera phones will be sold worldwide in 2002, and the report predicts that this figure will grow to 147 million in 2007.
The GX10 demonstrates the convergence of portability, connectivity and multimedia in a single platform.
High-speed communications, colour imaging and advanced power management rely on high performance signal processing technology.
ADI leads in the critical signal processing areas of amplifiers and data converters, technologies applied throughout the company's LCD, power management and wireless solutions.
The SoftFone GSM/GPRS chipset includes a mixed-signal interface as well as a baseband digital processor with both DSP (digital signal processing) and microcontroller cores.
These cores include sufficient processing speed to handle the phone functions as well as the camera and display-processing functions without the extra cost and power consumption of an external application processor.
The GX10 includes several pre-installed games, and uses Java to allow new games, ringtones, and third-party applications to be downloaded.
TTP Communications of Cambridge, England provided the GPRS protocol stack software.
