BlueCore3-Multimedia silicon is at the heart of the new BlueTrip from Griffin Technologies.
With tiny dimensions of 7 x 7mm, BlueCore3-Multimedia has minimum impact on the overall aesthetics of end-user products and allows for exceptionally compact Bluetooth devices.
Weighing barely 30g, the Motorokr S9 features has compact 1.3cm in-ear speakers and achieves up to 6h 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 8Mbit of internal Flash memory as well as an on-chip DSP and stereo CODEC.
The embedded Kalimba DSP core is an open platform coprocessor 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.
In addition, the Motorola stereo headphones use CSR's CVC.
CVC is an echo and noise-cancellation technology, 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 comments: "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".
