SAA7893HL
Super audio media player
Rev. 02 — 26 February 2003 Product data
1. General description
Thanks to the superior sound quality and multichannel capability of Super Audio CD
(SACD) technology, multimedia devices 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 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. This ensures that the SA-MP can be left
unchanged even if the SACD playback hardware is altered, again minimizing
development effort.
