Broadcom Corp. announced the availability of its CellAirity multimedia mobile phone product which is designed to enable manufacturers to develop handsets with leading-EDGE third-generation (3G) functionality at second-generation (2G) price points. The new WEDGE chipset is part of Broadcom's CellAirity mobile platform and provides advanced WEDGE (WCDMA + EDGE) connectivity to enable a new class of lower power, smaller size 3G handsets, with a total bill-of-materials under $100.

The CellAirity WEDGE chipset combines the EDGE standard with WCDMA, CellAirity. The company reports that it requires up to 30 percent less board space than competing products and provides a 50percent improvement in power consumption compared to earlier generations.

The CellAirity baseband chipset consists of the BCM2133 EDGE processor and BCM2141 WCDMA processor. The BCM2133 single-chip multimedia EDGE baseband is Broadcom's 3G of silicon featuring an ARM926EJ processor and fully monolithic mixed-signal elements for RF and audio connectivity. The BCM2133 also integrates a full set of multimedia features, including a 2 Megapixel digital camera, video record and playback capabilities, a stereo MP3 player, support for 64-tone polyphonic ringtones, and a "TV-out" feature allowing for low-cost EDGE or WEDGE devices while still enabling data services. The BCM2133 supports Broadcom's proprietary MStream cellular technology, which is designed to improve speech and signal quality.

WCDMA capabilities are enabled by the BCM2141 WCDMA co-processor, which is a full-featured WCDMA baseband that, when paired with the BCM2133 EDGE processor, enables seamless roaming between 2G and 3G networks. The device is an integrated digital and analog baseband solution for WCDMA (UMTS)/FDD and features an integrated 384Kbps class modem in downlink and uplink With low-power architecture to provide increased battery life, a complete level-1 firmware package, and a programmable RF interface for system design flexibility, the BCM2141 helps bring the most advanced phones to market in the short timeframes required by handset developers.

The BCM2133 and BCM2141 chipset is sampling now.
