The state-owned TD-SCDMA leading technology to break the monopoly of overseas mobile phone chip

Reported: "in Beijing in May 31st after entering 3G, the domestic mobile phone chip manufacturers will have more opportunities, especially the standard of TD-SCDMA, the domestic enterprises have been in the leading position." In May 26th, Spreadtrum vice president of communications Li Xiaohui told reporters that domestic enterprises are expected to borrow TD-SCDMA mobile phone manufacturers in Europe to break the monopoly of the core chip. In 2G mobile phone chip, control the European giants always market. In terms of CDMA, Qualcomm a dominant; in terms of GSM, TI, Infineon, PHILPS and other traditional giants together to carve up the market.

TD-SCDMA is the entry point

Spreadtrum communications is one of the earliest successful development of TD-SCDMA of the third generation mobile communication standard SoC based TD-SCDMA (LCR) communication manufacturers. At present, in the research of TD-SCDMA terminal companies have cooperation with Spreadtrum communications.

Li Xiaohui told reporters that the new version of the TD-SCDMA chip Spreadtrum are under development, but the industrialization of TD-SCDMA, the chip problem has been resolved, then more important products between the terminal and the network of commercial manufacturers.

It is reported that the Ministry of information industry on TD-SCDMA network system of commercial test scheduled for June this year, come to an end.

Li Xiaohui said that the current focus is on the development of Spreadtrum TD-SCDMA and GSM/GPRS chip, the key aspects of 2G in multimedia baseband chip, the WCDMA chip Spreadtrum will do, but not the focus. He said, TD-SCDMA is a new standard, many domestic enterprises including Spreadtrum from the beginning to R & D investment in this area, where relatively leading technology, domestic chip manufacturers also hope to make a breakthrough in the advantages of 3G core chip field.

In the field of CDMA2000, WCDMA, the international giant has been dominant in the core chip. Analysis of the industry, even from 2G transition to 3G, in CDMA2000, WCDMA two standard areas, shake the market position of these giants are not easy. Vimicro chief scientist Dr. Yu Qing told reporters that the baseband chip and RF chip technology content is very high, need long-term accumulation of technology, the traditional chip giant before entering the 3G has made a huge investment in R & D. After entering the 3G, they can still maintain this position in the market today.

Chip integration trends

The same day, Spreadtrum communications multimedia baseband processing chip of independent research and development (SC6600M), the chip has the baseband chip functions, also supports 1 million 300 thousand pixel digital camera and camera and playback, 64 chord + stereo sound, MP3 playback, USB interface, mobile phone support U disk function.

According to Spreadtrum communications company, SC6600M is the most integrated baseband and multimedia integration chip at present in the world. It will SM/GPRS modem, video, audio and other capabilities into the size of only 12mm * 12mm area on the chip.

Generally speaking, increasing the capture and playback of multimedia features such as mobile phone, mobile phone chip solution according to the general non integrated scheme to include video processing chip, audio chip, application coprocessor chip and so on, and the use of multimedia baseband processing chip integration core Spreadtrum the release (SC6600M) without the addition of other multimedia processing chip, can the function of all.

Li Xiaohui believes that the integration of mobile phone chips is a trend in the development of technology, it can reduce the phone's size, cost and power consumption, the development of mobile phone manufacturers can also reduce the degree of development responsibility. But he also acknowledged that the integration and non integration of the chip is two different directions, non integration also has its own advantages.

However, with the further strengthening of mobile phone functions, the trend of integration of mobile devices has become the direction of industrial development. More features, smaller volume, lower cost of the mobile phone assembly requirements of mobile phone components factory to solve the problem of less commercial function requirements, component manufacturers have a plurality of parts into a multi-function mobile phone component, at the beginning of the micro integration scheme.

From the development of some important chip manufacturers, single chip integrated development, reduce costs, reduce the volume is affected by many manufacturers of identity, baseband and RF integrated chip; mobile phone baseband DSP and microprocessor; baseband and application processors are becoming the new direction of development.

According to Spreadtrum communications source, SC6600M market is still in the promotion period, the second half of this year will be the mobile phone chip products.
