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 âHost Controller Power Managementâ 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
â Bluetooth clock request
â Bluetooth standard sniff
â 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
