1.3 Description

The TAS3202 is an audio system-on-a-chip (SOC) designed for mini/micro systems, multimedia-speaker,

and MP3 player docking systems. It includes analog interface functions: two multiplex (MUX) stereo inputs

with one stereo analog-to-digital converter (ADC) and one stereo digital-to-analog converter (DAC) with

analog outputs consisting of differential stereo line drivers. Four channels of serial digital audio processing

are also provided. The TAS3202 has a programmable audio digital signal processor (DSP) that preserves

high-quality audio by using a 48-bit data path, 28-bit filter coefficients, and a single-cycle 28×48-bit

multiplier. The programmability feature allows users to customize features in the DSP RAM.

The TAS3202 is composed of eight functional blocks:

1. Analog input/mux/stereo ADC

2. Stereo DAC

3. Analog reference system

4. Power supply

5. Clocks, digital PLL, and serial data interface

6. I²C control interface

7. 8051 microcontroller

8. Audio DSP – digital audio processing
