Description

TAS3218 is an audio system-on-a-chip (SOC) designed for digital television audio systems and mini/micro component applications. TAS3218 has a programmable audio DSP that preserves high-quality audio by using a 48-bit data path, 28-bit filter coefficients, and a single cycle 28 x 48-bit multiplier. The programmability feature allows users to customize features in the DSP RAM.

The TAS3218 is composed of seven functional blocks. Clock and serial data interfaceAnalog input and output M8051 WARP controller, serial control interface, and device controlAudio DSP digital audio processingPower supply Internal references

Figure 1 shows the functional structure of the TAS3218.
