DESCRIPTION

The STA015 is a fully integrated high flexibility

MPEG Layer III Audio Decoder, capable of decod-

ing Layer III compressed elementary streams, as

specified in MPEG 1 and MPEG 2 ISO standards.

The device decodes also elementary streams

compressed by using low sampling rates, as spec-

ified by MPEG 2.5. STA015 receives the input

data through a Serial input Interface. The decoded

signal is a stereo, mono, or dual channel digital

output that can be sent directly to a D/A converter,

by the PCM Output Interface.

This interface is software programmable to adapt

the STA015 digital output to the most common

DACs architectures used on the market. The func-

tional STA015 chip partitioning is described in

Fig.1a and Fig.1b.
