BCM4330 Preliminary Data Sheet
Features
• Narrowband and wideband packet loss concealment
• Scatternet operation with up to four active piconets with background scan and support for scatter mode
• High-speed HCI UART transport support with low-power out-of-band BT_WAKE and HOST_WAKE signaling
(see “Host Controller Power Management” on page 45)
• Channel quality driven data rate and packet type selection
• Standard Bluetooth test modes
• Extended radio and production test mode features
• Full support for power savings modes
– Bluetooth clock request
– Bluetooth standard sniff
– Deep-sleep modes and software regulator shutdown
• TCXO input and auto-detection of all standard handset clock frequencies. Also supports a low-power
crystal, which can be used during power save mode for better timing accuracy.
Major FM Radio features include:
• 65 MHz to 108 MHz FM bands supported (US, Europe, and Japan)
• FM subsystem control using the Bluetooth HCI interface
• FM subsystem operates from 32.768 kHz low-power oscillator (LPO) or reference clock inputs
• Improved audio interface capabilities with full-featured bidirectional PCM, I2S, and analog stereo DAC
• I2S can be master or slave
FM Receiver-Specific Features Include:
• Excellent FM radio performance with 1 µV sensitivity for 26 dB (S+N)/N
• Signal-dependent stereo/mono blending
• Signal dependent 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
• Automatic frequency jump
FM Transmitter-Specific Features Include:
• Programmable output power with +120 dBµV maximum output power and 24 dB range
• RDS and RBDS encoder and modulator with intelligent frame encoding and programmable scroll rate
• Programmable audio swing to FM modulation deviation
• Programmable mono or stereo transmission
• Concurrent Bluetooth v4.0 + EDR and FM transmit functionality
• Digital audio input from I2S or PCM
• Host programmable frequency from 76 MHz to 108 MHz in 50 kHz channel steps
• Digitally programmable audio level and mute control
