SAA6752HS/104

Product Summary

The SAA6752HS/104 is a MPEG-2 video and MPEG-audio/AC-3 audio encoder with multiplexer. The SAA6752HS/104 will also enable a key driver for new consumer digital recording applications and system cost reduction. By integrating all audio encoding and multiplexing functionality we will be moving from a three chip to a one chip system, with cost efficient design and process technology, thus providing a truly low cost, high quality encoding system. The SAA6752HS/104 is intended for customers whose application does not require the DDCE function.
