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.

• 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

• 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 matching

• Mobile handsets and smart phones
• Personal digital assistants
• Mobile MP3 players
