Functions Available in the External Digital Filter Mode
The external digital filter mode allows access to the majority of the DSD1792 mode control functions.
The following table shows the register mapping available when the external digital filter mode is selected, along with
descriptions of functions which are modified when using this mode selection.

The effective oversampling rate is determined by the oversampling performed by both the external digital filter and the
delta-sigma modulator. For example, if the external digital filter is 8
×
oversampling, and the user selects
OS[1:0] = 00, then the delta-sigma modulator oversamples by 8
×
, resulting in an effective oversampling rate of 64
×
. The
16
×
WDCK oversampling rate is not available above a 100-kHz sampling rate. If the oversampling rate selected is 16
×
WDCK, the system clock frequency must be over 256 f
