As noted earlier, the crystal should be placed very
close to the device to minimize excessive loading due
to parasitic capacitances. Care should also be taken to
minimize loading on pins that could be floated as a pro-
gramming option (SMSEL and CMSEL). Coupling on
inputs due to clocks should be minimized.

Layout Considerations
NOTE: IN THE ABOVE CONFIGURATION WITH PDN CONNECTED TO V
AND CMSEL FLOATING, THE DEVICE IS IN NORMAL OPERATION WITH 2x CLOCK MULTIPLICATION, AND
SPREAD-SPECTRUM MAGNITUDE OF ±0.5%.
