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.
Xin = 6.0 MHz
