Analog Devices Inc. (ADI) has started sampling Tier 1 mobile handset makers and local ODMs with a second-generation chipset that complies with the Chinese 3G TD-SCDMA Low Chip Rate (LCR) air interface.

Dubbed the SoftFone-LCR+, the part will be in volume production by the end of Q1 2007, and according to Jorgen Krogh, business development director, mobile network operators at ADI, handsets using the chipset should be available soon after that.

"In China, it is no longer a question of if, but when for 3G based on TD-SCDMA. Admittedly, we have been waiting a long time for the government to issue licenses for networks throughout the country, but trials are proceeding well and data rates using TD-SCDMA have now reached speeds of up to 384kbps in real-world conditions," said Krogh. "Now the handset makers have to ensure there are sufficient phones out there, both for those that want just voice-centric models and to meet the demand for those that opt for multimedia versions," Krogh told EE Times Europe.

ADI already supplies its chips in conjunction with software from its local partner, Datang Mobile, for at least 5 of the models used on the various trials using TD-SCDMA technology, including those from ZTE Corp., Holley Communications and Inventec, as well as those from design houses Longcheer and Simcom.

Krogh said the main European suppliers, such as Nokia, need to look seriously at this emerging market, but would not say which if any of the European suppliers or designers is considering using its SoftFone-LCR+ chipset.

The SoftFone-LCR+ chipset enables dual-mode TD-SCDMA/GPRS operation and achieves full 384kbps 3G performance, enabling faster download speeds, video streaming, video telephony and Web browsing capabilities critical requirements in supporting the migration to 3G wireless networks in China.
