CSR Launches World's First Integrated Bluetooth High Definition Audio Platform with Support for Ambient Noise Cancellation

CSR8675™ upgrade enables OEMs to differentiate products while providing consumers with higher quality audio

Cambridge, UK and San Jose, California, USA -- November 14, 2014 -- CSR plc (LSE:CSR; NASDAQ: CSRE) today announces the CSR8675™, its latest audio flash platform, designed specifically for high-end wireless audio products. Building on the success of the CSR8670™, the feature rich platform offers greater processing power than its predecessor, allowing manufacturers to deliver enhanced quality audio output and noise cancellation for high-end speakers, soundbars, stereo headsets and gaming headphones.

The CSR8675 contains an upgraded digital signal processor (DSP) core delivering increased performance of up to 120 MIPS, compared to the 80 MIPS DSP of its predecessor. This enables advanced audio processing algorithms to be supported allowing very high quality, enriched audio performance. Coupled with the chip’s 24 bit digital audio support, the high performance core ensures devices built upon the CSR8675 platform will deliver the high definition audio that is increasingly demanded by sophisticated consumers. As the chip supports aptX® Low Latency, it will also enable consumers to watch video while listening to wireless audio in a synchronised fashion.

“Audiophiles looking to buy the highest quality audio devices crave exceptional sound quality together with the convenience of wireless connectivity,” says Anthony Murray, Senior Vice President, Business Group at CSR. “The CSR8675 offers customers new processing power and a platform upon which they can significantly differentiate their high-end products while delivering a truly immersive listening experience to the end user.”

The CSR8675 platform includes new support for Ambient Noise Cancellation (ANC), replacing the standalone ANC IC technology used today in many popular headphones and headsets. The CSR8675 not only reduces the complexity of adding ANC, it also offers manufacturers significant eBoM cost savings and reduced solution size benefits.

By offering Bluetooth v4.1 support, CSR’s audio flash platform improves consumer usability while aiding developer innovation by allowing devices to support Basic Rate and EDR links as well as Bluetooth Smart connections.

CSR8675 key features:

• Increased DSP performance up to 120 MIPS
• Integrated high performance stereo DAC & ADCs
• 24 bit digital audio support
• 2 x I2S interfaces
• 1 x SPDIF interface
• 2 x additional GPIOs (over CSR8670)
• Bluetooth v4.1 support
• 16Mb internal eflash and up to 64Mb external serial flash
• 6 x Capacitive touch sensor inputs
• Up to six digital microphone inputs
• Support for ANC feed-forward architecture
