New Reference Design from Zeevo Featuring Wolfson Audio Codec Gives Manufacturers a Fast Track to CD-Quality Wireless
SANTA CLARA, Calif.--(BUSINESS WIRE)--Oct. 28, 2004--
Untethered MP3 Players, Wireless Speakers and Stereo Headphones
Expected to Dominate CES This Winter
Asian and other original device manufacturers (ODMs) that desire to catch the next
wave in lifestyle entertainment products will appreciate a new reference design from Zeevo using Wolfson audio CODECs that will enable them to design and introduce wireless stereo headsets, speakers or wireless MP3 players that feature true CD-quality sound -- well in time for the winter Consumer Electronics Show (CES). With the availability of these new products, based upon a new generation of low-cost quality audio Bluetooth wireless transceiver chips from Zeevo, coupled with Wolfson's celebrated single-chip CODECs, consumers will be able to dispense with the wires that have until now tethered their stereo headphones to the MP3 players on their arms and waists, or their high-quality speakers to their entertainment centers.
"This could be one of the hottest new trends that we see at CES this year," said Dr. David Milne, CEO of Edinburgh-based Wolfson Microelectronics, a world leader in high-performance mixed-signal chips. "Wolfson is delighted to be part of one of the first solutions to offer high quality wireless audio."
A reference design is a sample electronics circuit design that shows engineers how to utilize the latest developments in microchips in their own products. Using a reference design as a base, it is possible today for a device manufacturer to incorporate a new technology into existing designs in a few weeks, and have products available to ship not long after. The designs use the ZV4301 Zeevo Bluetooth ARM7-based microcontroller chip to process and transmit stereo data via the Bluetooth wireless standard, and any of Wolfson's WM8731, WM8711, WM8955 audio CODECs to perform audio coding and decoding, digital to analog and analog to digital conversions, and filtering.
"This is a real breakthrough for device manufacturers," said Jalil Shaikh, president and CEO of Zeevo. "Wireless audio in personal entertainment products has not previously been offered, because of an inability to meet the consumer's expectations for quality. Wolfson has solved the problem on the audio CODEC side, and we have solved that on the wireless side. What we are assuring is that the consumer will have an uncompromising, CD-quality audio experience, and that wires to headsets and speakers will become a thing of the past."
According to Shaikh, the reference design provides full CD-bandwidth, up to an 87dB signal-to-noise ratio (SNR), and receiver sensitivity of -86dBm. The Wolfson CODECs provide 98dB SNR in the DACs, which provides for excellent "total audio chain" performance.
The reference design is available from Zeevo today.

About Zeevo
Zeevo is a leading-edge semiconductor provider that designs and markets "system-on-a-chip" (SoC) lifestyle wireless products for use in consumer electronics products ranging from cellular phones to MP3 players to personal computers to loudspeakers. Zeevo's latest wave of products uniquely solve the problem of high quality audio over Bluetooth -- increasingly in demand as the wireless movement floods over in to headsets, stereo headphones, and loudspeakers. The company pioneered the concept of "Sound Design for Bluetooth(TM)," a quality, reliability and convenience benchmark for Bluetooth audio that includes high-quality audio, interference-free co-existence with 802.11 wireless, dynamic mode switching for convergence applications, and fail-soft out-of-range behavior.
Zeevo Bluetooth platforms integrate analog, digital, and radio-frequency (RF) circuitry, as well as memory and a programmable ARM7 processor, on a single-chip built using highly cost-effective, standard CMOS technology. Zeevo's chips are delivered in design- and manufacturing-friendly packages that incorporate all RF components, and are accompanied by Zeevo's advanced ZSound(TM) algorithms, CODEC interfaces, and operating software. This results in quality Bluetooth audio solutions that are distinguished by small size, low cost, low power consumption and ease of integration by OEMs and ODMs into market-leading end products.
Zeevo supports open, industry-standard development tools, and an easy-to-use application program interface (API) and development environment on its Bluetooth platforms, which enable customers to easily customize their solutions and deliver differentiated products.
Zeevo was founded September 1999 in Silicon Valley by industry veterans. Investors in the privately-held company include Sequoia Capital, Raza Venture, Focus Ventures, WK Technology Fund, Institutional Venture Partners (IVP), CDIB, Winbond, and Capital Group Companies.
