Refer to Digital Filter Characteristics section for an explanation of the different filter types.

All other combinations of BOSR and SR[3:0] that are not in the truth table are invalid The BOSR bit represents the base over-sampling rate. This is the rate that the WM8711/L digital signal processing is carried out at. In Normal mode, with BOSR = 0, the base over-sampling rate is at 256fs, with BOSR = 1, the base over-sampling rate is at 384fs. This can be used to determine the actual audio data rate required by the DAC. The exact sample rates achieved are defined by the relationships in Table 13 below. ACTUAL SAMPLING RATE BOSR=0 BOSR=1 TARGET SAMPLING RATE MCLK=12.288 MCLK=11.2896 MCLK=18.432 MCLK=16.9344 kHz kHz kHz kHz kHz 8 8.018 8 8.018 8 (12.288MHz/256) x 1/6 (11.2896MHz/256) x 2/11 (18.432MHz/384) x 1/6 (16.9344MHz/384) x 2/11 32 32 32 (12.288MHz/256) x 2/3 not available (18.432MHz/384) x 2/3 not available 44.1 44.1 44.1 not available 11.2896MHz/256 not available 16.9344MHz /384 48 48 48 12.288MHz/256 not available 18.432MHz/384 not available 88.2 88.2 88.2 not available (11.2896MHz/256) x 2 not available (16.9344MHz /384) x 2 96 96 96 (12.288MHz/256) x 2 not available (18.432MHz/384) x 2 not available Table 13 Normal Mode Actual Sample Rates |
