Spread Spectrum Clock Generation Technology
Benefits of Lexmark Modulation Waveform
The advantages of Lexmark’s modulation waveform for
EMI attenuation derive from its unique, patented shape,
one embodiment of which is shown in Figure 1. In Figure 3. Experimental Test Setup
addition to the shape shown in Figure 1, other waveforms
are covered by Lexmark patents (such as the triangular, or This setup simulates a 100 MHz 0.5% down-spread
linear, waveform). A less efficient ‘sharkfin’, or system clock. In this setup, the arbitrary waveform
exponential, waveform as see……
