BLUETOOTH® 2.0 + EDR SINGLE-CHIP HCI SOLUTION WITH INTEGRATED FM+RDS RADIO RECEIVER
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
SUMMARY OF BENEFITS
• Bluetooth 2.0 +EDR compliant with easy migration to future specification
• Low external BOM cost and small area with 10 external RLC
components. The PCB foot print is < 35 mm² area.
• Operates directly from a lithium battery or from fixed voltages down to
1.65 Volt
• Best-in-class RF performance for longest range and ease of system
integration
• Full featured FM system with RDS/RBDS capability
• FM system can operate independently from Bluetooth
• Highly flexible interfaces for control and data/audio routing
• Improved power dissipation for longer battery life
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 matching
APPLICATIONS
• ^{Mobile handsets and smart phones}
• ^{Personal digital assistants}
• ^{Mobile MP3 players}
