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.

2.2. Multichannel Decoder Family of
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
