Low cost smart phone reference design by Broadcom with 3G support

Broadcom Corporation has introduced the BCM21552G 1GHz 3G cellular baseband and complete reference design.

The new Broadcom BCM21552G 3G baseband integrates a 1GHz ARM11 processing core, high-performance graphics processing and support for dual-SIM configurations in a single chip to drive availability of lower cost smartphones that offer the same features as much higher-priced alternatives.

The reference design based on the new processor includes Broadcom's multi-band 2G/3G RF transceiver and its industry-leading InConcert connectivity suite, including dual-band (2.4 / 5GHz) Wi-Fi, Bluetooth 4.0, NFC, and a Global Navigation Satellite System (GNSS) navigation solution that leverages multiple satellite constellations (GPS and GLONASS) for faster and more accurate location capabilities. InConcert includes coexistence technology that allows its various connectivity components to work better together, providing a seamless user experience and reducing time to market for smartphone developers.

Key Facts:
The Broadcom BCM21552G baseband processor enables the next generation of smartphones by supporting 3GPP (3rd Generation Partnership Project) release 6 and 7 features, which provides up to 5.8 Mbps (Megabits per second) of upstream connectivity, 7.2 Mbps of downstream connectivity and support for next generation CS (circuit switched) over HSPA services.
The graphics core built into the BCM21552G baseband processor provides video support up to D1/VGA quality, support for an 8 megapixel camera, and the ability to encode and decode H.264 video at 30 fps (frames per second).
The reference design features BCM4330 Bluetooth 4.0/Wi-Fi 802.11n/FM radio combo chip, the BCM47511 Global Navigation Satellite System (GNSS) solution, the BCM20791 NFC solution, and the BCM2091 2G/3G cellular RF transceiver.
