Wolfson Releases World's Leading Feature-Rich Integrated Multichannel CODEC for AV Systems

SAN DIEGO & EDINBURGH, United Kingdom--July 21, 2004--Wolfson Microelectronics plc (LSE:WLF.L) today released the WM8777, the latest generation of its multi-channel CODEC family. The WM8777 leads the industry in integrated audio signal processing capability. When combined with a commercially available DSP, this single mixed-signal device provides all the major audio functions for next generation of 5.1, 6.1 and 7.1 Audio-Visual systems, including DVD receivers, flat panel televisions and other multi-media home and automotive equipment.

The WM8777 CODEC integrates a high performance 8-channel DAC, 2-Channel ADC, with what Wolfson considers to be the highest performing four input Digital Interface Transceiver (S/PDIF) of its type, as well as bass management, stereo mix-down, tone and volume control for both 5.1 analogue inputs and digital playback sources. The WM8777 is also the only commercially available chip of this kind to provide a secondary audio interface, which allows the S/PDIF interface to run independently of the CODEC audio interface, a vital feature simplifying customer designs.

"The WM8777 integrates the functions of what is currently often done in 3 separate devices," said Jason Coughlan. "By integrating these functions alongside leading S/PDIF performance and the unique secondary interface, WM8777 is the logical choice for customers wishing to reduce design complexity and save cost. No other solution can offer this package of benefits."

Each of the 8 DAC channels has a Master Volume Control, with a gain range of +20dB to -100dB in 1dB steps. The WM8777 provides full 7.1 Channel support or 5.1 operation, whilst simultaneously supporting auxiliary remote room audio. Sampling rates range from 8kHz to 192kHz and the integrated stereo headphone amplifier includes source selection. A single serial interface on the WM8777 provides access to all the features and extensive digital routings offer additional flexibility.

Price and Availability

The WM8777 is available in a 100-pin TQFP package priced at $7.34 (US) in quantities of 10,000.
