Table 12 Normal Mode Actual Sample Rates
128/192FS NORMAL MODE
The Normal Mode sample rates are designed for standard 256Fs and 384Fs MCLK rates. However
the WM8711 is also capable of being clocked from a 128/192Fs MCLK for application over limited
sampling rates as shown in the table below.

Table 13 128/192Fs Normal Mode Sample Rate Look-up Table
512/768FS NORMAL MODE
512 Fs and 768 Fs MCLK rates can be accommodated by using the CLKIDIV2 bit. The core clock to
the DSP will be divided by 2 so an external 512/768 MCLK will become 256/384 Fs internally and the
device otherwise operates as in Table 10 but with MCLK at twice the specified rate.
