Introduction
The Micronas MAS 3528E is a single-chip Dolby Digital and MPEG-1 Layer-2 decoder. Together with the Surround Sound Processor DPL 4519G, it acts as a complete implementation of a Dolby Digital consumer decoder. In a television environment, these two integrated circuits are complemented by the Micronas Multistandard Sound Processor MSP 4450G which performs the standard TV sound decoding.
