True global phone chip platform supports both WCDMA and TD-SCDMA

August 16, 2012 // By Nick Flaherty
Marvell is claiming to be the first with a breakthrough global 3G chip platform supporting both WCDMA and the Chinese TD-SCDMA standards.

The single unified 3G platform features a single-chip application and communications processor System-on-Chips (SoCs) combined with Marvell's latest Wi-Fi + Bluetooth + FM radio + Near Field Communications (NFC) + GPS chip, RF transceivers and integrated PMIC solutions for both Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Wideband Code Division Multiple Access (WCDMA) markets.

With pin-to-pin compatibility, original equipment manufacturers (OEMs) can use the same printed circuit board (PCB) and ID designs, and operating system, application and multimedia software to address both the WCDMA and TD-SCDMA markets, which is expected to greatly simplify design cycles and reduce unnecessary cost. Engineering samples for the unified platform are available now.

Designed specifically for the China 3G TD-SCDMA market, the 1.2 GHz dual core ARM Cortex A9 PXA988 is the next generation of the highly ubiquitous PXA920 family of mobile processors that powers millions of smartphones in China. It is equipped with an integrated image signal processor (ISP), advanced graphics processing unit (GPU) that can achieve 192 million triangles per second (MT/s) and a breakthrough 533 MHz LPDDR2 memory architecture for enhanced CPU and system performance. The PXA988 features a TD-HSPA+ R8 modem which supports dual-carrier aggregation and represents the next-generation of TD-SCDMA technology. The new advanced modem also supports Dual SIM Dual Talk, which enables users to activate two services on a single smartphone, and Downlink Dual Carrier (DLDC).

The PXA986 1.2 GHz dual-core mobile processor was designed for WCDMA markets and is pin-to-pin compatible with the PXA988, effectively streamlining and reducing costs for OEM design cycles. Powered by the identical high-performance application processor subsystem as the PXA988, OEMs can seamlessly re-use their operating system and multimedia software across both mobile platforms to minimize design resources and decrease time to market. The PXA986 features a HSPA+ R7 modem, which supports 21.1 Mbps download data-rate and 5.76 Mbps upload data-rate, making it a viable solution for 4G smartphones. The PXA986 modem
