Description

The CS493XX is a family of multichannel audio decoders

intended to supersede the CS4923/4/5/6/7/8/9 family as the

leader of audio decoding in both the DVD, broadcast and

receiver markets. The family will be split into parts tailored for

each of these distinct market segments.

For the DVD market, parts will be offered which support Meridian

Lossless Packing (MLP), Dolby Digital, Dolby Pro Logic II,

MPEG Multichannel, DTS Digital Surround, DTS-ES, AAC, and

subsets thereof. For the receiver market, parts will be offered

which support Dolby Digital, Dolby Pro Logic II, MPEG

Multichannel, DTS Digital Surround, DTS-ES, AAC, and various

virtualizers and PCM enhancement algorithms such as HDCD

DTS Neo:6

broadcast market, parts will be offered which support Dolby

Digital, AAC, MPEG-1, Layers 1,2 and 3, MPEG-2, Layers 2 and

Under the Crystal brand, Cirrus Logic is the only single supplier

of high-performance 24-bit multi-standard audio DSP decoders,

DSP firmware, and high-resolution data converters. This

combination of DSPs, system firmware, and data converters

simplify rapid creation of world-class high-fidelity digital audio

products for the Internet age.
