Description

The TAS3208 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable 48-bit digital audio processor, 10:1 stereo analog input MUX, stereo ADC, six DACs, and other analog functionality. The TAS3208 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop development environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3208’s digital audio processing core.

TAS3208 processing capability includes speaker equalization and cross over, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third party or TI royalty-free algorithms.

The TAS3208 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. A stereo, 93-dB DNR ADC and six 97-dB DNR DACs ensure that high-quality audio is maintained through the whole signal chain.

The TAS3208 is composed of seven functional blocks:

  • Clock and serial data interface
  • Analog input and output
  • M8051 WARP controller, serial control interface, and device control
  • Audio DSP – digital audio processing
  • Power supply
  • Internal references

Figure 1 shows the functional structure of the TAS3208.
