Datang Mobile selects Freescale's DSP for TD-SCDMA Node-B basestations

October 17, 2006

As Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology ramps in China as the official standard for 3G mobile telephone service, Freescale Semiconductor continues to win major wireless basestation designs. Datang Mobile Communications Equipment, one of China's largest government-owned telecom equipment manufacturers, has selected Freescale's MSC8122 quad-core DSP based on StarCore technology for its TD-SCDMA Node-B basestations.

"As commercial use of the TD-SCDMA standard gains momentum in China, Freescale is working closely with leading telecom equipment makers like Datang to support system-level solutions that speed 3G network deployment," said David Perkins, senior vice president and general manager of Freescale's Networking and Computing Systems Group. "Freescale looks forward to working with Datang to realize the truly profound opportunity that this standard holds for the Chinese market."

The adoption of TD-SCDMA technology promises to dramatically reduce air interferences and increase system capacities, which are highly suitable for operators' asymmetrical data services. The technology is proficient in dynamically adjusting data transmission rates with uplink and downlink. It also efficiently handles circuit and IP-switched voice and video data payloads, as well as packet data to and from the Internet.

"Freescale's MSC8122 quad-core DSP offers the optimal balance of high performance, low power and programmability that Datang needs for its next-generation TD-SCDMA Node-B basestation designs," said Li Feng, vice president of Datang Mobile. "Freescale is a leader in communications processing with technology that can help Datang continue to provide world-class products to its customers."

In addition to the MSC8122, Datang also leverages the power and performance of PowerQUICC processors and RF products from Freescale in its next-generation TD-SCDMA Node-B basestation.

About the MSC8122 DSP

Freescale's MSC8122 quad-core DSP based on StarCore technology is highly optimized for high-bandwidth and computationally intensive DSP applications, such as wireless transcoding, packet telephony and wireless basestation applications. The MSC8122 DSP is designed to deliver enhanced performance while maintaining low power dissipation and can greatly reduce system cost.

Delivering performance equivalent to a 2GHz single-core DSP, the MSC8122 provides an optimal solution for 3G wireless basestations by reducing the number of DSPs in the system and many of the costly, power-hungry companion ASICs and FPGAs required for both symbol rate and chip rate assist. In addition, when leveraging the full programmability of the MSC8122 device, customers can add next-generation features that efficiently use available frequencies and higher bit rates in 3G systems.
