8.3.11.4 Decimation Filter

The TLV320ADC3100 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. Decimation filtering is achieved using a higher-order cascaded integrator-comb (CIC) filter followed by linear-phase FIR filters. The decimation filter cannot be chosen by itself; this filter is implicitly set through the chosen processing block.

This section describes the properties of the available filters A, B, and C.
