APPLICATIONS
This IC is mainly intended for use in Digital Versatile Disc
(DVD) players. However it may also be used in any
application that is able to accept an MPEG2 audio
bitstreams such as:
Set top boxes
Multimedia PCs
Digital television
Next generation audio equipment.
GENERAL DESCRIPTION
The SAA2503 incorporates all necessary functions, such
as MPEG2 multichannel audio decoding plus
down-mixing, MPEG1 layer 2 decoding, Linear PCM
(LPCM) processing all producing high quality audio.
Together with the serial audio interfaces and the IEC 958
transmitter this allows for the complete audio function of a
DVD player in a single chip.
