QWhat is the recommended treatment for power and grounding of the AD9249 to
achieve data sheet performance?
AWhen connecting power to the AD9249, it is recommended that two separate 1.8 V
supplies be used. Use one supply for analog (AVDD); use a separate supply for
the digital outputs (DRVDD). A single PCB ground plane should be sufficient
when using the AD9249. With proper decoupling and smart partitioning of the PCB
analog, digital, and clock sections, optimum performance can be easily
