Description
The CS4923/4/5/6/7/8 is a family of multi-channel digital
audio decoders, with the exception of the CS4929 as the
only stereo digital audio decoder. The CS4923/4/5/6 are
designed for Dolby Digital and MPEG-2 Stereo decoding. In
addition the CS4925 adds MPEG-2 multi-channel decoding
capability and the CS4926 provides DTS decoding. The
CS4927 is an MPEG-2 multi-channel decoder and the
CS4928 is a DTS multi-channel decoder. The CS4929 is an
AAC 2-channel and MPEG-2 stereo decoder. Each one of
the CS4923/4/5/6/7/8/9 provides a complete and flexible
solution for multi-channel (or stereo in the case of the
CS4929) audio decoding in home A/V receiver/amplifiers,
DVD movie players, out-board decoders, laser-disc players,
HDTV sets, head-end decoders, set-top boxes, and similar
products.
Cirrus Logic’s Crystal Audio Division provides a complete set
of audio decoder and auxiliary audio DSP application
programs for various applications. For all complementary
analog and digital audio I/O, Crystal Audio also provides a
complete set of high-quality audio peripherals including:
multimedia CODECs, stereo A/D and D/A converters and
IEC60958 interfaces. Of special note, the CS4226 is a
complementary CODEC providing a digital receiver, stereo
A/D converters, and six 20-bit DACs in one package.
