CY25818/19 SSCG products use a non-linear "optimized"
frequency profile as shown in Figure 6 and Figure 7. The use
of Cypress proprietary "optimized" frequency profile maintains
flat energy distribution over the fundamental and higher order
harmonics. This results in additional EMI reduction in
electronic systems.
