Requirements for System Clock
For operation in the DSD mode, the bit clock (DBCK) is required on pin 7 of the PCM1796. 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 DSDL and DSDR is required to meet the setup and hold time
specifications shown in Figure 44.
