Feature
This mode is used for interfacing directly to a DSD decoder, which is found in Super Audio CD (SACD) applications.
The DSD mode is accessed by programming the following bit in the corresponding control register.
DSD = 1 (register 20)
The DSD mode provides a low-pass filtering function. The filtering is provided using an analog FIR filter structure.
Four FIR responses are available, and are selected by the DMF[1:0] bits of control register 18.
The DSD bit must be set before inputting DSD data; otherwise, the PCM1796 erroneously detects the TDMCA mode,
and commands are not accepted through the serial control interface.
Pin Assignment When Using DSD Format Interface
Several pins are redefined for DSD mode operation. These include:
DATA (pin 5): DSDL as L-channel DSD data input
LRCK (pin 4): DSDR as R-channel DSD data input
SCK (pin 7): DBCK as bit clock for DSD data
BCK (pin 6): Set LOW (N/A)
