DSD - SWITCHING CHARACTERISTICS
Logic 0 = GND; VLS = 1.8 V to 5.5 V; Logic 1 = VLS Volts; C
Note: 19. Min is 4 times 64x DSD or 2 times 128x DSD, and Max is 12 times 64x DSD or 6 times 128x DSD. The
Master Clock Frequency

DSD_SCLK Pulse Width Low
DSD_SCLK Pulse Width High
DSD_SCLK Frequency
DSD_L / _R valid to DSD_SCLK rising setup time
DSD_SCLK rising to DSD_L or DSD_R hold time
proper MCLK to DSD_SCLK ratio must be set either by the DIF registers or the M0:2 pins
