Thanks to the superior sound quality and multichannel capability of Super Audio CD (SACD) technology, multimedia SAA7893HL such as DVD players and home cinema systems are incorporating SACD functionality. Philips' Super Audio Media Player (SA-MP) provides a flexible, state-of-the-art solution for SACD playback on DVD architectures.

Built around the SAA7893HL SACD processor, SA-MP system solution delivers complete SACD functionality, avoiding the need for continual redesign and re-integration of SACD into various applications. The system SAA7893HL is completed with a single 64 Mbit SDRAM and has extensive software processing options, resulting in low total system cost (see Figure 1).

With integrated support for multiple loaders, the SAA7893 supports a variety of DVD platforms. High level and standard software interfaces optimized for easy design-in further enhance adaptability, enabling designers to build SACD players on many different hardware and software platforms. SAA7893HL ensures that the SA-MP can be left unchanged even if the SACD playback hardware is altered, again minimizing development effort.
