6.4.2 Direct DSD Conversion (DIR_DSD)
6.4.3 Static DSD Detect (STATIC_DSD)
6.4.4 Invalid DSD Detect (INVALID_DSD)
6.4.5 DSD Phase Modulation Mode Select (DSD_PM_MODE)
6.4.6 DSD Phase Modulation Mode Enable (DSD_PM_EN)
Function:
When set to 0 (default), DSD input data is sent to the DSD processor for filtering and volume control func-
tions.
When set to 1, DSD input data is sent directly to the switched capacitor DACs for a pure DSD conversion.
In this mode, the full-scale DSD and PCM levels will not be matched (see
performance may be reduced, the volume control is inactive, and the 50 kHz low pass filter is not available
(see
Function:
When set to 1 (default), the DSD processor checks for 28 consecutive zeroes or ones and, if detected,
sends a mute signal to the DACs. The MUTEC pins will eventually go active according to the DAMUTE
register.
When set to 0, this function is disabled.
Function:
When set to 1, the DSD processor checks for greater than 24 out of 28 bits of the same value and, if de-
tected, will attenuate the data sent to the DACs. The MUTEC pins go active according to the DAMUTE
register.
When set to 0 (default), this function is disabled.
Function:
When set to 0 (default), the 128Fs (BCKA) clock should be input to DSD_SCLK for Phase Modulation
Mode. (See
When set to 1, the 64Fs (BCKD) clock should be input to DSD_SCLK for Phase Modulation Mode.
Function:
When set to 1, DSD phase modulation input mode is enabled, and the DSD_PM_MODE bit should be set
accordingly.
When set to 0 (default), this function is disabled (DSD normal mode).
