Cambridge Silicon Radio has released its third-generation single-chip silicon, marking a major step in the evolution of Bluetooth silicon.
Bluetooth chip keeps headsets in tune
The BlueCore3-Multimedia chip is being used by i.Tech Dynamic for a new Bluetooth stereo headset that enables users to receive phone calls while listening to music on their wireless headphones.
Most significantly, the Jabra BT800 employs the digital signal processing (DSP) technology in BlueCore3-MM for improved sound quality and for noise reduction.
The Jabra BT800 is currently shipping in Europe, the Middle East and Africa at Eur 149 and is expected to roll out to the US and Asia Pacific markets in the coming months.
CSR's BlueCore3-MM complies with both the v1.1 and v1.2 Bluetooth standards allowing the Jabra BT800 to connect to any Bluetooth-enabled mobile phone on the market.

Bluetooth chip adds more to stereo headphones
BlueCore3-Multimedia silicon provides the Bluetooth connectivity behind Motorola's new feature-rich HT820 Bluetooth stereo headphones.
BlueCore3-MM offers: eSCO (enhanced synchronous connection oriented) voice channels to ensure that no part of the voice transmission is lost due to corruption of data packets; and adaptive frequency hopping (AFH) which further minimises potential interference from other radio devices.
The on-chip DSP, which is integrated into the CSR Bluetooth chipset, has given the Jabra engineers the opportunity to make great advancements in the reduction of background noise.
The Jabra BT800 will change volume settings according to the surrounding conditions where the call is made.
Therefore, when talking in a noisy street or on a train, the headset will automatically adjust the volume of the call to counteract any ambient noise.
"Jabra and CSR have worked together on a number of projects bringing feature-rich Bluetooth headsets to accommodate the rapidly evolving mobile phone market", commented Niels-Henrik Valentin Knudsen, Senior Product Manager, Jabra.
"CSR's BlueCore technology helps us to continually push the boundaries of Bluetooth headset design and offer our customers premium quality products with innovative design".
Luke D'Arcy, Product Manager, CSR added: "Sound quality and battery consumption remain the most important features of a Bluetooth headset".
"The integrated DSP of BlueCore3-MM combined with the standard features of v1.2 Bluetooth to ensure optimum sound quality without signal degradation, and very low power consumption".
"The Jabra BT800 offers an attractive package of quality and features to satisfy the changing design and functionality demands placed on the next generation of Bluetooth headsets".
