11 Layout
11.1 Layout Guidelines
•
The PCM514x family of devices are simple to layout. Most engineers use a shared common ground for an
entire device. GND can consider AGND and DGND connected.
•
Good system partitioning should keep digital clock and interface traces away from the analog outputs for
highest analog performance. This reduces any high-speed clock return currents influencing the analog
outputs.
•
Power supply and charge pump decoupling capacitors should be placed as close as possible to the device.
•
The top layer should be used for routing signals, whilst the bottom layer can be used for GND.
11.2 Layout Example
It is recommended to place a top layer ground pour for shielding around the DAC and connect to lower main PCB
ground plane by multiple vias
