7.3.3.1.1 Processing Blocks

The TLV320DAC3203 offers a range of processing blocks which implement various signal processing capabilities along with decimation filtering. These processing blocks give users the choice of how much and what type of signal processing they may use and which decimation filter is applied.

Table 2 gives an overview of the available processing blocks and their properties.

The signal processing blocks available are:

  • First-order IIR
  • Scalable number of biquad filters
  • Variable-tap FIR filter

The processing blocks are tuned for common cases and can achieve high anti-alias filtering or low group delay in combination with various signal processing effects such as audio effects and frequency shaping. The available first order IIR, BiQuad and FIR filters have fully user-programmable coefficients. The Resource Class Column (RC) gives an approximate indication of power consumption.
