Integrated multichannel Codec awakens next-gen AV Systems

San Diego, US and Edinburgh, UK — Wolfson Microelectronics plc releases 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.

Each of the 8 D/A converter channels has a master volume control, with a gain range of +20dB to -100dB in 1 dB steps. The WM8777 provides full 7.1 Channel support or 5.1 operation, while simultaneously supporting auxiliary remote room audio. Sampling rates range from 8 kHz to 192 kHz 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.

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