TAS3202数据手册集成电路（IC）的DSP（数字信号处理器）规格书PDF

描述 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:
Analog input/mux/stereo ADC Stereo DAC Analog reference system Power supply Clocks, digital PLL, and serial data interface I2C control interface 8051 microcontroller Audio DSP – digital audio processing
