Objective specification
MPEG2 audio decoder
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. ORDERING INFORMATION TYPE NUMBER SAA2503HT PACKAGE NAME LQFP100 DESCRIPTION plastic low profile quad flat package; 100 leads; body 14 x 14 x 1.4 mm APPLICATIONS
SAA2503
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.
