Feature
This mode is used for interfacing directly to a DSD decoder, which is found in Super Audio CD
t (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.
