2.
The CS49300 family contains system on a chip
solutions for multichannel audio decompression
and digital signal processing. The CS49300 family
is split into 4 sub-families targeted at the DVD,
broadcast and audio/video receiver (AVR), and
effects and post processing markets.
This document focuses on the electrical features
and characteristics of these parts. Different features
are described from a hardware design perspective.
It should be understood that not all of the features
portrayed in this document are supported by all of
the versions of application code available. The
application code user’s guides should be consulted
to confirm which hardware features are supported
by the software.
The parts use a combination of internal ROM and
RAM. Depending on the application being used, a
download of application software may be required
each time the part is powered up. This document
uses “download” and “code load” interchangeably.
These terms should be interpreted as meaning the
transfer of application code into the internal
memory of the part from either an external
microcontroller or through the autoboot procedure.
2.1. Multichannel Decoder Family of Parts
CS49300 - DVD Audio Decoder. The CS49300
device is targeted at audio decoding in the DVD via
ES or PES in a serial or parallel bursty fashion for
MLP or for DVD Audio Pack Layer Support. (All
the other decoding/processing algorithms listed
below require delivery of PCM or IEC61937-
packed compressed data via I
digital audio to the CS49300). Specifically the
CS49300 will support all of the following
decoding/processing standards:
•
•
DS339PP4
