SSCG Profiles
CY25811/12/14 SSCG products use a non-linear “optimized”
frequency profile as shown In
Figure 3
. 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.
