The OS bit in the DSD mode is used to select the operating rate of the analog FIR. The OS bits must be set before setting
the DSD bit to 1.
Requirements for System Clock
The bit clock (BCK) for the DSD mode is required at pin 3 of the DSD1792. The frequency of the bit clock can be N times
the sampling frequency. Generally, N is 64 in DSD applications.
The interface timing between the bit clock and DATAL and DATAR is required to meet the same setup- and hold-time
specifications as shown for the audio interface timing in Figure 42.
