MPEG2 audio decoder
Objective specification
SAA2503
FEATURES
• Single-chip MPEG2 multichannel audio decoder
• Decodes MPEG high quality audio:
– MPEG1 layer 2 (44.1 kHz)
– MPEG2 multichannel layer 2 (48 kHz)
– Supports pause frames
• Outputs 2 channels
– Quasi surround down-mixing for Left and Right Dolby
surround channel (Lt and Rt)
– Stereo down-mixing for stereo reproduction
– Stereo signal selection
– Single channel down-mixing
• Karaoke modes
• Linear PCM modes:
– Down-sampling from 96 to 48 kHz
– Pass 48 kHz signals
• Bitstream input interface I2S-bus (IEC 1937 formatted)
• IEC 958 output interface (IEC 1937 formatted)
• IEC 958 output simultaneously available while decoding
MPEG2
• I2C-bus control
• Output flags for direct control
• Stand-alone operation possible (self-booting)
• No external DRAM or SRAM required
• On-chip PLL for internal clock generation
• 13.5 or 27 MHz master clock
• 100 pins plastic LQFP package
• 5 V power supply.
APPLICATIONS
This IC is mainly intended for use in Digital Versatile Disc
(DVD) players. However it may also be used in any
application that is able to accept an MPEG2 audio
bitstreams such as:
• Set top boxes
• Multimedia PCs
• Digital television
• Next generation audio equipment.
GENERAL DESCRIPTION
The SAA2503 incorporates all necessary functions, such
as MPEG2 multichannel audio decoding plus
down-mixing, MPEG1 layer 2 decoding, Linear PCM
(LPCM) processing all producing high quality audio.
Together with the serial audio interfaces and the IEC 958
transmitter this allows for the complete audio function of a
DVD player in a single chip.
