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