DSD Serial Clock
The master clock frequency must be either 4x or 6x the DSD data rate for 64x oversampled DSD data
and 2x or 3x the DSD data rate for 128x oversampled DSD data, refer to Table 7.
This pin determines the allowable Master Clock to DSD data ratio as defined in Table 7.
Clocks the individual bits of the DSD audio data into the DSD_L and DSD_R pins.
Direct Stream Digital audio data is clocked into DSD_L and DSD_R via the DSD serial clock.
