This document is a preliminary specification for Philips Semiconductors SAA2500 MPEG Audio Source Decoder. The decoder features advanced error protection, integrated audio post processing for control of signal level and inter-channel crosstalk, demultiplexing of ancillary data in the input bitstream, automatic digital de-emphasis of the decoded audio signal, separate master and slave inputs, automatic sample frequency and bit-rate switching in master input mode, automatic synchronization of input and output interface clocks in master input mode, selectable audio output precision of 16, 18, 20 or 22 bits, and low power consumption. It is suitable for applications such as cable and satellite digital radio decoders, video CD, Compact Disc Interactive (CD-I), sold-state audio, and Multimedia Personal Computer (PC).
The Philips SAA2500 is an integrated circuit designed as a MPEG Audio Source Decoder. It supports all audio modes (joint stereo, stereo, single channel, and dual channel) at bit rates and sample frequencies standardized in ISO/IEC 11172-3 for Layers I and II.
Key features include advanced error protection, integrated audio post-processing for signal level control and inter-channel crosstalk management, demultiplexing of ancillary data, automatic digital de-emphasis, and selectable audio output precision ranging from 16 to 22 bits. The device is suitable for applications such as cable and satellite digital radio decoders, Video CD, Compact Disc Interactive (CD-I), and Multimedia Personal Computers.
The plastic quad flat package measures 10 x 10 x 1.75 mm.
