PRINTED CIRCUIT BOARD LAYOUT
A typical PCB floor plan for the DSD1700 is shown in
Figure 11. A ground plane is recommended, with the analog
and digital sections being isolated from one another using a
split in the plane. The DSD1700 should be oriented with the
digital I/O pins facing the ground plane split/cut, allowing
for direct connection to the DSD decoder and control signals
originating from the digital section of the board.
Separate power supplies are recommended for the digital
and analog sections of the board. This prevents the switching
noise present on the digital supply from contaminating the
analog power supply and degrading the dynamic perfor-
mance of the DSD1700.
