Figure 30. Recommended PCB Layout
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 performance of the PCM1753/54/55. In cases where a common 5-V supply must be used for the
analog and digital sections, an inductance (RF choke, ferrite bead) should be placed between the analog and
digital 5-V supply connections to avoid coupling of the digital switching noise into the analog circuitry. Figure 31
shows the recommended approach for single-supply applications.
