元器件交易網訊 11月15日消息，根據(jù)Digitimes研究，一些IC供應商已經開始提供支持TD-LTE的芯片，包括基頻芯片、射頻芯片、應用處理器、SoC解決方案和軟調制解調器，目前為止，基頻芯片占TD-LTE芯片出貨量的大部分份額。

由于產品標準高，供應商有限，TD-LTE芯片的平均銷售價格預計將保持穩(wěn)定。然而，國內芯片組供應商將逐步提高其硬體規(guī)格，并進入該領域，迫使國際品牌供應商專注于更先進的設備，如應用處理器和SoC。

中國移動計劃在2014年正式推出TD-LTE服務，已要求芯片供應商提供TD-LTE芯片，該芯片支持五種模式，分別是LTE/LTE FDD、TD-LTE、TD-SCDMA、WCDMA和GSM）以及10個工作頻率帶。

由于芯片規(guī)格較高，因此能滿足該要求的芯片組供應商大多是國際廠商，其中包括高通、Marvell科技與聯(lián)發(fā)科。國內大多數(shù)IC設計公司，除了深圳市海思半導體，不太可能最初進入中國移動的供應鏈。（元器件交易網郭路平 譯）

Digitimes Research: ASPs of TD-LTE chips to remain stable initially as suppliers are limited

While a number of IC vendors have begun shipping chips supporting TD-LTE, including base band chips, radio frequency chips, application processors, SoC solutions and soft modems, shipments of base band chips account for a majority share of total TD-LTE chip shipments currently, according to Digitimes Research.

China Mobile, while planning to officially launch TD-LTE services in 2014, has required chipset suppliers offer TD-LTE chips supporting five modes (LTE/LTE FDD, TD-LTE, TD-SCDMA, WCDMA and GSM) and also 10 operational frequency bands.

Since the specifications are high, chipset suppliers which can meet the requirements are mostly international players, including Qualcomm, Marvell Technology and MediaTek. Most IC design houses in China, with the exception of HiSilicon Technologies, are unlikely to enter China Mobile's supply chain initially.

ASPs of TD-LTE chips are expected to remain stable initially because of high product standards and limited suppliers. However, local chipset suppliers in China are expected to gradually enhance their hardware specifications and to step into the segment with aggressive pricing later, forcing international brand vendors to focus on more sophisticated devices such as application processors and SoCs, said Digitimes Research.
