CSR plc (LSE:CSR) the wireless technology provider and world leader in Bluetooth connectivity, today announced that its BlueCore3-Multimedia (BlueCore3-MM) silicon is at the heart of the new BlueTrip from Griffin Technologies. The Bluetooth accessory enables users to wirelessly broadcast and control CD-quality music from an Apple iPod to any home stereo environment or compatible A2DP compliant Bluetooth stereo headphones. Griffin Technologies' decision to use BlueCore3-MM in delivering Bluetooth wireless connectivity, assures the BlueTrip a reliable connection while co-existing with other 2.4GHz radios. The BlueTrip is available now worldwide.

The BlueTrip wireless transmitter clips onto the iPod through the audio output jack and transmits CD-quality music directly to the BlueTrip receiver attached to a home stereo or AV system. The transmitter is powered directly from the iPod creating no need to charge the unit separately. The stylish receiver is powered by a 12v DC power supply and features RCA stereo plugs as well as optical S/PDIF and mini-jack output allowing for compatibility with any home stereo. The BlueTrip is compatible with the 3G and 4G iPods along with the iPod mini and iPod photo.

BlueCore implements a host of profiles including A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Visual Remote Control Profile). AVRCP permits the BlueTrip to act as a remote control unit for a connected Bluetooth device. The A2DP profile allows advanced audio to be transmitted from the music player to devices such as Bluetooth stereo headphones or a home stereo. BlueCore3-MM's integrated DSP also means that the device requires no external processor for audio analysis, thus saving money on the associated bill of materials. The BlueCore3-MM DSP is also more efficient in audio processing, achieving power consumption levels similar to that of Bluetooth mono headsets. This allows the BlueTrip to have a small impact on the battery life of the iPod and enjoy a longer playing time.

CSR offers a range of standard solutions and technologies for customers designing Bluetooth multimedia products. CSR's BlueLab 3.2 software development kit allowed Griffin Technologies Inc. to take these standard solutions and customise them for their own distinct offering. The in-built protected user mode, enabled by BlueLab, means that customer software cannot interfere with the Bluetooth operation of the chip. This protection feature all but obviates the need for re-testing.

Mark Rowan, Engineering Manager for Griffin Technologies commented, "Our new BlueTrip device uses the best Bluetooth technology and the highest quality components on the market. CSR's expertise has allowed us to achieve the highest possible sound quality and a highly attractive product." Mark continued, "Thanks to CSR's support, we have been able to introduce Bluetooth connectivity to our iTrip offerings with ease and minimal time to market."

Luke d'Arcy, product marketing manager for CSR commented, "Griffin Technologies demanded the highest Bluetooth audio quality for their BlueTrip. CSR was able to offer the most cost-effective, high-performance multimedia silicon and software package on the market. Through the use of BlueLab software we were able to offer Griffin a truly customised, leading Bluetooth solution without them incurring increased costs."

About CSR

CSR plc is the leading global provider of Bluetooth technology and has developed expertise in other single-chip wireless communication standards such as Wi-Fi (IEEE802.11). CSR offers developed hardware/software solutions for Bluetooth based around BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller.

CSR has now launched its fifth generation BlueCore suite and is in volume manufacture of its fourth generation BlueCore devices. BlueCore4 supports the Enhanced Data Rate (EDR) standard, which was ratified at the end of 2004. BlueCore4 remains the only EDR silicon to be shipping in volume today. In November 2004 CSR launched UniFi, the first single chip 802.11a/b/g embedded solution specifically targeting the mobile phone and consumer electronics markets.

BlueCore features in over 50 per cent of all Bluetooth devices shipped and over 60 per cent of all qualified Bluetooth enabled products and modules listed on the Bluetooth website with industry leaders including Nokia, Dell, Panasonic, Sharp, Motorola, IBM, Apple, NEC, Toshiba, RIM and Sony using BlueCore devices in their range of Bluetooth products.

In March 2005, CSR acquired Clarity Technologies Inc., for its Clear Voice Capture (CVC) technology that enhances the audio performance of any voice-based product or system. Applications for CVC include wireless headsets, handsets and automotive hands free systems.

In August 2005, CSR completed the acquisition of UbiNetics' software business, providing a strong R&D team to accelerate its existing software development in Bluetooth, Wi-Fi and UWB. The UbiNetics team gives CSR the capacity to extend its offering to mobile handset customers.

CSR has its headquarters and offices in Cambridge, UK, and offices in Japan, Korea, Taiwan, China, India, France, Denmark, Sweden and both Texas and Detroit in the USA.
