3.2 16 kHz-48 kHz Sample Rate

All processing blocks and digital filter options are supported for the 16 kHz to 48 kHz sample rates.

The decimation filter can be configured to linear phase, low latency, or ultra-low latency. AGC or DRE is supported for all analog channels. Bi-quads, channel summers, and digital mixer blocks are supported on their respective input channels (Table 2-7). Figure 3-1 shows the channel combinations supported for an 8 kHz operation. These remain the same. For a supported channel combination, the cell entry in Figure 3-1 indicates the number of bi-quads available for that channel combination.
