New audio platform from CSR for Bluetooth mono headset

CSR has released the BC6145, a Bluetooth audio platform for single-microphone mono headsets, speakerphones, car-kits and other mass-market wireless audio accessories. BC6145 is the first ROM based mono device to support a new set of consumer-centric features including High Definition voice ("HD voice") call quality, A2DP music streaming and advanced intelligibility enhancements. BC6145 also features bi-directional noise reduction and ultra low power Wind Noise Reduction (WNR).

CSR says with the prevalence of A2DP supported music streaming in media players and handsets, a large proportion of consumers will benefit from BC6145's ability to play music from high-quality A2DP audio sources.

BC6145 employs bi-directional noise reduction, Wind Noise Reduction (WNR) algorithm along with the send path noise reduction to improve the quality of incoming audio. WNR only switches on when it detects the presence of wind noise,

The BC6145 uses CSR's 6th Generation of CVC speech enhancement software which provides a collection of algorithms that enable advanced audio features including packet loss and bit error concealment that ensure audio quality in difficult RF environments.

Anthony Murray, Senior Vice President of CSR's Audio and Consumer Business Unit comments: "CSR's expertise in wireless audio platform technology has made possible the most feature rich, low cost ROM solution available today. For the first time, a Bluetooth device for the mass-market affordable headset, speakerphone and car-kit sectors is offering exciting new features like HD voice and the ability to listen to high-quality music. In doing so, BC6145 is truly redefining the value proposition for these platform segments and enabling a vastly improved consumer experience."

As well as low-cost mono headsets, BC6145 is also suitable for mass-market car-kits and speakerphones.

Package: QFN package, pin compatible with BC6140.
