CSR Powers MOTOROKR S9 Bluetooth Stereo Headphones

CSR plc announced that its BlueCore3-Multimedia silicon is inside the new MOTOROKR S9, Bluetooth stereo headphones. Due for release in the first half of 2007, the high quality headphones utilise CSR’s BlueCore3-Multimedia’s integrated DSP and CVC (Clear Voice Capture) technology. With a tiny 7x7mm form factor, BlueCore3-Multimedia has minimum impact on the overall aesthetics of end-user products and allows for exceptionally compact Bluetooth devices.

MOTOROKR S9 Bluetooth Stereo HeadphonesWeighing barely an ounce, the MOTOROKR S9 features compact 1.3 cm in-ear speakers and achieves up to six hours of playback from a single charge. Compatible with Bluetooth-enabled stereo music phones and MP3 players, the behind-the-head style headphones offer fingertip control of music and voice calls as well as automatic music muting.

CSR’s BlueCore3-Multimedia is a single chip Bluetooth radio and baseband IC with 8Mbits of internal Flash memory as well as an on-chip DSP and stereo CODEC. The embedded Kalimba DSP core is an open platform co-processor that supports enhanced audio applications such as echo and noise cancellation. BlueCore3-Multimedia has been designed to reduce the number of external components required which ensures production costs are minimised while also incorporating auto-calibration and use cases to simplify development, type approval and production tests.

In addition, the Motorola stereo headphones use CSR’s CVC. CVC is a world-leading echo and noise cancellation solution, which adapts to a number of different environments in order to enhance voice communications. Rather than suppressing noise like many competing technologies, CVC separates out the voice signals using proprietary time-domain signal extraction and improves audio quality regardless of hardware deployment, audio interface, operating system or speech recognition applications.

Anthony Murray, Vice President of CSR’s Wireless Audio Business Unit commented, “CSR’s products and services demonstrate the company’s commitment to providing device manufacturers with the highest level of performance and adaptability. CSR’s family of wireless ICs enable designers to easily incorporate wireless functionality into a variety of design concepts ensuring a high-level of innovation and function.”
