Freescale Semiconductor is helping accelerate the build-out of China's Time Division Synchronous Code Division Multiple Access (TD-SCDMA, a third-generation wireless standard that is being widely adopted throughout China) networks, leveraging deep industry relationships and a broad technology portfolio for wireless infrastructure equipment. According to the China TD-SCDMA Technology Forum, TD-SCDMA deployments are expected to be completed in 30 cities by the end of 2008, translating to 3 million users and a 15% nationwide penetration rate by 4Q09.
Adoption of Freescale technology for TD-SCDMA networks is gaining momentum. Spreadtrum Communications, a leading Chinese TD-SCDMA chipset vendor, recently designed Freescale's MC34673 battery charger IC into its TD-SCDMA 8800D platform. Additionally, several of China's top TD-SCDMA equipment manufacturers leverage advanced DSPs based on StarCore technology, and Freescale's market-leading PowerQUICC processors are commonly deployed in TD-SCDMA installations throughout the country.
"Freescale maintains a deep portfolio of DSP, microprocessor and RF technologies ideal for the creation of highly advanced TD-SCDMA equipment", said Kai Wang, Vice-President of Sales & Marketing and General Manager of the Asia-Pacific Region for Freescale. Leveraging the breadth of its technology portfolio, which includes StarCore DSPs, PowerQUICC communications processors and RF devices optimised for TD-SCDMA, the company is "supplying OEMs with silicon solutions engineered to deliver the performance, power and enablement capabilities necessary to meet NGN demands."
In 2007, Freescale introduced the industry's first multi-stage commercial RFICs optimized for TD-SCDMA applications. The high output levels of the MW7IC2240NB RFIC allow OEMs to reduce part counts from two or three devices to one, saving board space and reducing power consumption and cost. The company is continuing to invest in TD-SCDMA technology and plans to introduce next-generation RF parts in the months ahead.
Last year, Freescale opened a major design centre in Chengdu intended to serve as Freescale's primary operation for the development of TD-SCDMA technologies. Work at the centre also contributes significantly to the creation of next-generation RF products, as well as the advancement of microprocessor enablement technology.
