Figure 34. Connection Diagram for External DIgital Filter (Internal DF Bypass Mode) Application
Application for Interfacing With an External Digital Filter
For some applications, it may be desirable to use an external digital filter to perform the interpolation function, as it
can provide improved stop-band attenuation when compared to the internal digital filter of the DSD1793.
The DSD1793 supports several external digital filters, including:
D Texas Instruments DF1704 and DF1706
D Pacific Microsonics PMD200 HDCD filter/decoder IC
D Programmable digital signal processors
The external digital filter application mode is accessed by programming the following bit in the corresponding control
register:
D DFTH = 1 (register 20)
The pins used to provide the serial interface for the external digital filter are shown in the connection diagram of
Figure 34. The word clock (WDCK) signal must be operated at 8
× or 4× the desired sampling frequency, fS.
