Features
Processes MPEG audio with support for Linear PCM data.
Decodes dual-channel MPEG audio, Layer I and II ISO 13818-2,
supporting bit rates of 8 Kbps to 448 Kbps and sampling rates of 16,
22.05, 24, 32, 44.1, and 48 kHz.
Supports Linear PCM streams with sample rates of 48 kHz and
96 kHz at 24-bit resolution.
IEC958 output interface for audio data bitstreams.
Mute on error for concealment.
Provides an audio “Bypass” mode for interface to a CD audio
decoder.
Programmable preparser accepts PES, ES, and PS streams.
Direct connection to commodity SDRAM.
Input/output interfaces are optimized for glueless integration into
consumer video systems.
Operates from a single 27-MHz clock with an additional audio
sample clock input.
Total external memory required for audio and video decoding is
16-Mbit SDRAM for ITU-R BT.601-5 resolution.
Interfaces to Intel and Motorola (and compatible) 8-bit
microcontrollers for initialization, testing, and status monitoring.
Direct interface to off-the-shelf NTSC/PAL video encoders.
Direct interface to off-the-shelf audio stereo DACs.
Available in a 160-pin, PQFP pack.
Low power 3.3-Volt process.
TTL-compatible I/O pins.
