Audio Decoder 44-Pin TQFP T/R

The STA013 is a fully integrated high flexibility MPEG Layer III Audio Decoder, capable of decoding 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 specified by MPEG 2.5.STA013 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 STA013 digital output to the most common DACs architectures used on the market.

SINGLE CHIP MPEG2 LAYER 3 DECODER SUPPORTING: All features specified for Layer III in ISO/IEC 11172-3 (MPEG 1 Audio) All features specified for Layer III in ISO/IEC 13818-3.2 (MPEG 2 Audio) Lower sampling frequencies syntax extension, (not specified by ISO) called MPEG 2.5
