Product Summary
The STA013 is a MPEG 2.5 layer III audio decoder. 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 STA013 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 of the STA013is 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.
