Armed with the Time Machine II and blank field-programmable parts, designers can address system level EMI issues in two ways depending on the source of the EMI – whether it be from the clock trace or the SoC being clocked. If noise is generated from the clock trace that drives digital logic, a fast clock edge may radiate EMI energy. The Time Machine II can be used to program lower drive strength, which in turn slows the rise/fall time and reduces EMI radiation at higher harmonics. Rise/fall times in the range of 0.25 ns to 45 ns can be achieved by selecting and programming the applicable drive strength. See the data-sheet table on drive strength and rise/fall times for details.
