Table 12 Normal Mode Sample Rate Look-up Table
Notes:
1.
2.
The BOSR bit represents the base over-sampling rate. This is the rate that the WM8951L 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 produced by the ADC.
SAMPLING
8k not exact, actual = 8.018kHz
All other combinations of BOSR and SR[3:0] that are not in the truth table are invalid
