Marvell chipset unifies TD-SCDMA and WCDMA
Marvell has designed a 3G chipset for both Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Wideband Code Division Multiple Access (WCDMA) markets.
The unified 3G design incorporates an application and communications processor with wireless chips for Wi-Fi and Bluetooth, FM radio and Near Field Communications (NFC) and GPS, RF transceivers and power management.
“I believe Marvell’s advanced, single unified dual-core 3G platform will deliver high-performance, affordable smartphones and tablets to the global mass market,” said Weili Dai, co-founder of Marvell.
The PXA988 and PXA986 SoCs are based around 1.2GHz dual-core processors with wireless modems.
Designed specifically for the China 3G TD-SCDMA market, the dual-core PXA988 features Cortex A9 1.2GHz processors and full 1080p encode/decode capability, which makes it suitable for high-quality multimedia playback and video capturing.
It has an integrated image signal processor, advanced graphics processing unit that can achieve 192 million triangles per second (MT/s) and a 533MHz LPDDR2 memory architecture for enhanced CPU and system performance.
There is on chip a TD-HSPA+ R8 modem which supports dual-carrier aggregation. 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 single-chip, dual-core mobile processor was designed for WCDMA markets and is pin-to-pin compatible with the PXA988.
