BCM4356 Advance Data Sheet
Adaptive Frequency Hopping
Audio Rate-Matching Algorithms
The BCM4356 has an enhanced rate-matching algorithm that uses interpolation algorithms to reduce audio
stream jitter that may be present when the rate of audio data coming from the host is not the same as the
Bluetooth or FM audio data rates.
Codec Encoding
The BCM4356 can support SBC and mSBC encoding and decoding for wideband speech.
Multiple Simultaneous A2DP Audio Stream
The BCM4356 has the ability to take a single audio stream and output it to multiple Bluetooth devices
simultaneously. This allows a user to share his or her music (or any audio stream) with a friend.
FM Over Bluetooth
FM Over Bluetooth enables the BCM4356 to stream data from FM over Bluetooth without requiring the host to
be awake. This can significantly extend battery life for usage cases where someone is listening to FM radio on
a Bluetooth headset.
Burst Buffer Operation
The BCM4356 has a data buffer that can buffer data being sent over the HCI and audio transports, then send
the data at an increased rate. This mode of operation allows the host to sleep for the maximum amount of time,
dramatically reducing system current consumption.
Adaptive Frequency Hopping
The BCM4356 gathers link quality statistics on a channel by channel basis to facilitate channel assessment and
channel map selection. The link quality is determined using both RF and baseband signal processing to provide
a more accurate frequency-hop map.
