• Multipoint operation with up to seven active slaves

– Maximum of seven simultaneous active ACL links

– Maximum of three simultaneous active SCO and eSCO connections with scatternet support

• 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 37)

• 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 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
