External Digital Filter Interface and Timing
The DSD1793 supports an external digital filter interface with a 3- or 4-wire synchronous serial port, which allows
the use of an external digital filter. External filters include the Texas Instruments DF1704 and DF1706, the Pacific
Microsonics PMD200, or a programmable digital signal processor.
In the external DF mode, PLRCK (pin 1), PBCK (pin 2) and PDATA (pin 3) are defined as WDCK, the word clock;
BCK, the bit clock; and DATA, the monaural data, respectively. The external digital filter interface is selected by using
the DFTH bit of control register 20, which functions to bypass the internal digital filter of the DSD1793.
When the DFMS bit of control register 19 is set, the DSD1793 can process stereo data. In this case, DSDL (pin 25)
and DSDR (pin 24) are defined as L-channel data and R-channel data input, respectively.
Detailed information for the external digital filter interface mode is provided in the APPLICATION FOR EXTERNAL
DIGITAL FILTER INTERFACE section of this data sheet.
Direct Stream Digital (DSD) Format Interface and Timing
The DSD1793 supports the DSD format interface operation, which includes out-of-band noise filtering using an
internal analog FIR filter. The DSD format interface consists of a 3-wire synchronous serial port, which includes DBCK
(pin 4), DSDL (pin 25), and DSDR (pin 24). DBCK is the serial bit clock. DSDL and DSDR are L-channel and
R-channel DSD data input, respectively. They are clocked into the DSD1793 on the rising edge of DBCK. PLRCK
(pin 1) and PBCK (pin 2) must be connected to GND in the DSD mode. The DSD format (DSD mode) interface is
activated by setting the DSD bit of control register 20.
Detailed information for the DSD mode is provided in the APPLICATION FOR DSD FORMAT (DSD MODE)
INTERFACE section of this data sheet.
