Chapter 1
SLEU092 – February 2008
Overview
The TAS3208EVM PurePath Digital™ customer evaluation amplifier module demonstrates the Digital
Audio Processor TAS3208/TAS3208IA from Texas Instruments (TI).
TAS3208DCP/TAS3208IADCP is a fully programmable high-performance audio processor. It uses an
efficient, custom, multi-instruction programming environment optimized for digital audio processing
algorithms. The TAS3208/TAS3208IA architecture provides high-quality audio processing by using a 48-bit
data path, 28-bit filter coefficients, and a single-cycle 28- × 48-bit multiplier with a 76-bit accumulator. An
embedded 8051 microprocessor provides algorithm and data control for the TAS3208/TAS3208IA. The
TAS3208 is the commercial version intended for home audio and other commercial applications.
This is a signal board EVM. The EVM is delivered together with two boards – an input board with SPDIF,
ACD, and USB for PC control, and a output board with DACs and SPDIF transmitter. This system is a
complete 8-channel digital audio processor system that includes digital input/output (S/PDIF), analog
inputs/outputs, interface to PC and DAP features, such as digital volume control, input and output mixers,
auto mute, equalization, tone controls, loudness, dynamic range compression, and surround effects.
TAS3208 applications include digital televisions, home theater systems, mini-component audio systems,
and pro audio.
