APPLICATION FOR DSD FORMAT (DSD MODE) INTERFACE
FEATURES
This mode is utilized for interfacing directly to a DSD
decoder, found in Super Audio CD (SACD) applications.
DSD Mode provides a low-pass filtering function to convert
the 1-bit oversampled data stream to the analog domain. The
filtering is provided using an Analog FIR filter structure.
Four FIR responses are available and may be selected via the
serial control interface. Refer to the Typical Performance
Curves section of this data sheet for Analog FIR plots. See
Figures 1 and 2 for interface timing and specification, and
Figures 17 and 18 for timing and interface specification in
DSD mode.
PIN ASSIGNMENT WHEN IN DSD
FORMAT INTERFACE
Several pins are redefined for DSD Mode operation. These
include:
DATA (Pin 5)
DATAL, L-Channel DSD Data Input
MUTE (Pin 15)
DATAR, R-Channel DSD Data Input
SCKI (Pin 7)
Bit Clock (BCK) for DSD Data (64 x 44.1kHz)
LRCK (Pin 4)
Set LOW
BCK (Pin 6)
Set LOW
Typical connection to a DSD decoder is shown in Figure 11.
