The TLV320ADC3101 offers three different types of decimation filters. The integrated digital decimation filter
removes high-frequency content and downsamples the audio data from an initial sampling rate of AOSR × fS to
the final output sampling rate of fS. The decimation filtering is achieved using a higher-order CIC filter followed by
linear-phase FIR filters. The decimation filter cannot be chosen by itself; it is implicitly set through the chosen
processing block.
The following subsections describe the properties of the available filters A, B, and C.
