Cirrus launches audio processor with CobraNet controller and audio DSP engine

Austin, Texas — Cirrus Logic Inc.'s new family of audio system processors, which include a 120-Mips DSP, along with a CobraNet communications processor in a single chip, can reduce audio system costs, and enhance audio processing features for networked digital audio products.

The CS4961XX family of ICs integrates Cirrus Logic's 32-bit audio optimized 49K series of audio digital signal processors (DSP) with its CobraNet technology, a standard for delivering real-time, uncompressed digital audio over Ethernet networks.

The CS4961XX audio system processor series currently includes the CS496102, the CS496112 and the CS496122. The advanced audio system processors are designed to expand the market for digital audio processing coupled with CobraNet-enhanced networked digital audio products for such applications as power amplifiers, mixers, signal processors, intercom systems, ceiling speakers, loudspeakers and paging systems.

The added DSP power provides additional audio management features. For example, in professional audio products the DSP-based IC architecture enables feedback extermination in networked loudspeakers. In commercial audio products the ICs can be used for noise masking and/or ambient level sensing in structures such as hotels, airports, convention centers or office buildings. For consumer audio products, the ICs can be used to provide high-end, multichannel surround-sound digital audio processing for home theater applications.

The CS496102 supports two channels of simultaneous audio in/out; the CS496112 supports eight channels of simultaneous audio in/out; and the CS496122 supports 16 channels of simultaneous audio in/out.


The CS496102, CS496112 and CS496122 are available in a 144 LQFP package and are priced at $18.00, $21.60, and $23.26, respectively, in 10,000-piece quantities. Click here for additional technical information.
