Highly integrated electronic systems with high operation frequencies tend to radiate much electromagnetic noise at the main operation clock frequency and its harmonics. The resulting high peaks in the frequency spectrum may lead to disturbances of other electronic devices.
SSCG can reduce electro magnetic interference (EMI) by a slight clock modulation:
