Analog Devices, Anagram Technologies, and Cambridge Audio Deliver Richly Detailed Sound from Standard CDs

Power and performance of Blackfin processor drive Q5 Upsampling technology to produce High-quality, low distortion sound for new audio CD player

Norwood, MA (9/12/2006) - Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced that Cambridge Audio is leveraging ANAGRAM's proprietary Q5™ Upsampling technology, which runs on Blackfin to deliver superior, richly detailed sound from ordinary CDs. ANAGRAM selected Blackfin based on the processor's ability to handle multiple control and audio signal processing tasks on a single chip. The new player from Cambridge Audio, an international hi-fi leader, is geared to the mid- to high-end audio market and provides consumers with superior sound quality with staggeringly low distortion, low noise floor and a superior form of sound reproduction.

The Blackfin processor's digital signal processing functionality was critical to the project. Its high-performance memory and processing architecture enabled ANAGRAM to optimize the Q5 technology to deliver 384 kHz upsampling with better than 144 THD+N (total harmonic distortion plus noise) for 24-bit, 192 kHz digital audio input streams, a level of distortion unmatched by other audio algorithms. In effect, this allows existing standard CDs to play back with the enhanced audio clarity, richness and dynamic range normally associated with SACD or DVD-A disks.

“Analog Devices has earned its reputation for providing high-quality audio processing and mixed-signal products that deliver exceptional performance and value,” said Thierry Heeb, CEO at ANAGRAM Technologies SA. “The Blackfin processor's digital signal processing and microcontroller functionality enabled us to deliver an integrated solution with a level of performance at the right cost.”

Q5 Upsampling from ANAGRAM uses the ADSP-BF532 Blackfin processor to interpolate and resynchronize CD data to a level of audio quality that even matches the original master recordings. For the 840C, Cambridge Audio then fed the interpolated data through two AD1955 24-bit digital-to-analog converters (DACs) also from Analog Devices. The DACs, each an integrated, single chip stereo digital audio playback system provide dual-channel, 24-bit, 384 kHz audio, enabling the 840C to play back standard CDs with breakthrough crispness.

The integrated microcontroller functionality of the ADSP-BF532 enabled control of all the audio sub-systems in the 840C, including the digital audio receiver, digital audio transmitter, twin D/A converters and audio mutes – effectively removing the need and cost of including a separate host processor.

“The unique capabilities of Blackfin enable our customers to innovate and deliver differentiated products to the high-fidelity audio market,” said John Croteau, General Manager, Convergent Platforms and Services Group, Analog Devices. “Blackfin provides an integrated, flexible, low-cost solution that is ideal for audio applications that require a processor that can handle multiple control and signal processing instruction sets.”

A Convergent Future Demands Blackfin-Class Processing

Analog Devices' Blackfin® embodies a new breed of 16/32-bit embedded processor with the industry's highest performance and power efficiency for applications where a convergence of capabilities – multi-format audio, video, voice and image processing; multi-mode baseband and packet processing; and real-time security and control processing – are critical. It is this powerful combination of software flexibility and scalability that has gained Blackfin widespread adoption in convergent applications such as digital home entertainment; networked and streaming media; automotive telematics and infotainment; and digital radio and mobile TV.
