192 kHz Sample Rate

All three decimation filter options are supported for 192 kHz operation.

Figure 3-4 shows the channel combinations supported for 192 kHz sample rate with linear phase decimation filter response when AGC, DRE, or DRC is enabled. Figure 3-5 shows the combinations supported without AGC, DRE, or DRC. Bi-quads, channel summers, and digital mixer are supported with the linear phase decimation filter option.

For the low latency (and ultra-low latency) decimation filter response option, a maximum of three channels are supported when AGC, DRE, or DRC is disabled. Only one channel is supported when AGC, DRE, or DRC is enabled. Bi-quads, channel summers, and digital mixer are not supported for this mode.
