Description
The CS493XX is a family of multichannel audio decoders
intended to supersede the CS4923/4/5/6/7/8 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, MPEG
Multi-Channel, DTS and subsets thereof. For the receiver
market, parts will be offered which support Dolby Digital,
MPEG Multi-Channel, DTS, AAC and subsets thereof.
For the broadcast market parts will be offered which
support Dolby Digital, MPEG Advanced Audio Coding
(AAC), and MPEG Multi-Channel.
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 products.
