BCM43455 Preliminary Data Sheet
Features
• Trigger Broadcom fast connect (TBFC)
• 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_DEV_WAKE and
BT_HOST_WAKE signaling (see “Host Controller Power Management” on page 40)
• 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
• 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 reference clock inputs.
• Improved audio interface capabilities with full-featured bidirectional PCM and I2S
• 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
