CS49300 Family DSP
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
3.
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.
