BCM2048KUBG

The Broadcom BCM2048 is a monolithic 0.13 um single-chip Bluetooth® 2.0 +EDR compliant stand-alone baseband processor with an integrated 2.4-GHz transceiver, integrated FM and RDS/RBDS receiver, and an integrated FM baseband processor. It features the highest level of integration and eliminates all critical external components, thus minimizing the footprint and system cost of implementing a Bluetooth and FM solution. The BCM2048 is firmware upgradeable to future specifications. The BCM2048 is the optimal solution for any voice and/or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI) via a high-speed UART and PCM. The BCM2048 incorporates all Bluetooth 2.0 +EDR features including eSCO, AFH, fast connect, all EDR packet types and lengths, and all errata. The BCM2048 also includes InConcert and other industry collaborative coexistence solutions with WLAN systems.BLUETOOTH FEATURES • Monolithic single die integration of Bluetooth and FM Radio • Bluetooth specification 2.0 +EDR compliant with all data packet types and lengths supported • Best-in-class Bluetooth radio based on the proven BCM2045 core • Supports class 1 and 2 designs • Integrated InConcert™ 2-wire as well as industry standard 3-wire collaborative coexistence with WLAN systems • No factory alignment required • 5.5 Volt preregulator allows direct connect to lithium batteries • Improved Bluetooth transport with 4-Mbaud UART • Includes numerous enhancements for lower power dissipation • ROM-based solution with flexible code patching • Available in WLCSP 0.6 mm height and FPBGA <1 mm height FM + RDS RADIO FEATURES • 76-MHz to 108-MHz FM bands supported (US, Europe, and Japan) • Excellent radio performance with 1 uV sensitivity for 26 dB (S+N)/N • FM control through either BSC-compatible interface or Bluetooth HCI • Signal dependant stereo/mono blending • Signal dependant soft mute • Auto search and tuning modes • Audio silence detection • RSSI, IF frequency, status indicators • RDS and RBDS demodulator and decoder with filter and buffering functions • Operates from 32-kHz or reference clock inputs • Flexible output interfaces including PCM, I2S, and analog stereo DAC and drivers. • Integrated FM and RDS receiver with only one external cap, one external inductor and optional antenna matchingAPPLICATIONS • Mobile handsets and smart phones • Personal digital assistants • Mobile MP3 players
