DS1080L
Layout Considerations
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 open as a pro-
gramming option (SMSEL and CMSEL). Coupling on
inputs due to clocks should be minimized.

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