3.3 96 kHz Sample Rate

All three decimation filter options are supported for 96 kHz operation. 96 kHz mode supports AGC, DRE, or DRC processing blocks, but not for all channel combinations. Figure 3-2 shows the channel combinations supported when AGC, DRE, or DRC is enabled. Figure 3-3 shows the channel combinations support when AGC, DRE, or DRC is disabled.
