PCM1600, PCM1601
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 D/A converters. In cases where a common +5V
supply must be used for the analog and digital sections, an
inductance (RF choke, ferrite bead) should be placed be-
tween the analog and digital +5V supply connections to
avoid coupling of the digital switching noise into the analog
circuitry. Figure 18 shows the recommended approach for
single-supply applications.
PCB LAYOUT GUIDELINES
A typical PCB floor plan for the PCM1600 and PCM1601 is
shown in Figure 17. A ground plane is recommended, with
the analog and digital sections being isolated from one
another using a split or cut in the circuit board. The PCM1600
or PCM1601 should be oriented with the digital I/O pins
facing the ground plane split/cut to allow for short, direct
connections to the digital audio interface and control signals
originating from the digital section of the board.
