When laying out a board containing a MAX30003, the critical items to place and route first are:

  1. Analog components: Vref, CPLL, VBG, CAPP/N, VCM  
  2. VDD bypass caps
  3. ECG Filters:  
  4. These all need to be placed as physically close to the MAX30003 part as possible.  All other components should not interfere with the goal of getting these as close as possible, as those are sensitive lines.  
  5. They should not run out to any test point, as that will act as an antennae as well, and we want to keep the analog lines as clean as possible.  Please remove any unnecessary test points, open footprints, etc.
