STMicroelectronics STA014B
The STA014 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 elementarystreams compressed by using low sampling rates, as specified by MPEG 2.5. 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.APPLICATIONS

STA014 receives the input data through a Serial Input Interface. This interface is software programmable to adapt the STA014 digital output to the most common DACs architectures used on the market. The functional STA014 chip partitioning is described in Fig.1a and Fig.1b. July 2000 This is preliminary information on a new product now in development or undergoing evaluation.
