Preliminary specification
Stereo filter and codec for MPEG layer 1
audio applications
SAA2520
FEATURES
Stereo filtering and codec functions in a single chip
MPEG coded interface
Filtered data interface
Baseband audio data interface
LT interface to microcontroller
Clock generator
Low operating voltage capability.
GENERAL DESCRIPTION
The SAA2520 performs the sub-band filtering and audio
frame codec functions to provide efficient audio
compression/decompression for MPEG (11172-3) Layer1
applications. It is capable of functioning as a stand-alone
decoder but requires the addition of an adaptive masking
threshold processor (SAA2521) in order to function as a
highly efficient encoder.
