Enabling cost-effective,
value-added products
The IBM MPEG-2 digital audio/video
decoders, CS24, CS24E, CS24D,
and CS24DE, are advanced, high-
performance chips designed to satisfy
the needs of customers developing
professional audio/video products.
These single-chip decoders are
intended for professional audio/video
editing, broadcast, and a range of
emerging applications.
The IBM family of CS24 decoders
can decode MPEG-2 4:2:2 Profile at
Main Level video, Main Profile at Main
Level (MP @ ML) video, and MPEG-2
stereo Layers I & II (CD-quality) audio.
The CS24D and CS24DE also offer
the ability to decode Dolby® Digital
audio.* The new members of the
CS24 decoder family, the CS24E
and CS24DE, provide all of the features
of their counterparts (the CS24 and
CS24D, respectively) with enhance-
ments such as encoded Dolby Digital
pass-through. Together, these four
CS24 decoders give our customers a
broad selection of functionality for
designing value-added products
quickly and affordably.
A flexible, single-chip solution for
high-performance systems
IBM’s family of CS24 decoders
features an integrated transport
stream demultiplexer, MPEG-2 video
decoder, dual audio decoders, and
an SDRAM interface. By integrating
these features on a single chip, the
decoders enable more complex
designs while helping to reduce
design time and effort.
Integrated transport
stream demultiplexer
The integrated transport stream
demultiplexer accepts continuous
input at a rate of up to 160 Mb/sec in
parallel format or 60 Mb/sec in serial
format. Compliant with the ISO/IEC
13818-1 system layer standard, it
incorporates a range of capabilities.
These include data error reporting
and concealment, programmable
PID and table filtering, and flexible
packet-data routing. These features
assist in the design of very-high-
performance, complex systems
using fewer external components.

MPEG-2 video decoder
The integrated video decoder is
compliant with the ISO/IEC 13818-2
standards for 4:2:2 Profile at Main
Level video and MP @ ML video
decoding. In addition, the video
decoder is capable of decoding both
elementary streams and packetized
elementary streams at rates of up to
50 Mb/sec. This capability enables
high-bandwidth broadcast and
studio-quality applications.
The video decoder offers features
that provide design flexibility for
emerging, high-performance applica-
tions. Horizontal and vertical filtering,
pan and scan, on-screen display
support, 3:2 pulldown support, VBI
output support, and audio and video
synchronization are all incorporated
into these decoders. An on-chip
SDRAM memory interface, supporting
4-MB and 8-MB memory configura-
tions, helps enable more flexible,
affordable designs.
Dual audio decoders
The dual audio decoders, which can
operate simultaneously, support
robust designs like multi-language
applications requiring multiple audio
streams. The decoders can be
configured to decode MPEG-1 and
MPEG-2 Layers I & II audio in
compliance with the ISO/IEC
13818-3 standard and can also
decode Dolby Digital audio, thereby
providing the latest technology for
digital and audio systems. The entire
family of CS24 decoders offers a
built-in phase-locked loop for audio/
video synchronization and the
flexibility to support multiple audio
sampling rates and outputs.
Tools for simplied design
To assist customers in their product
development efforts, IBM offers
design tools, including an evaluation
card and card schematics.
