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

SSCLK1 = 6.0 MHz

S1, S0 = 0

FRSEL = 0

P/N = CY25811

Xin = 24.0 MHz

SSCLK1 = 24.0 MHz

S1, S0 = 0

FRSEL = M

P/N = CY25811

Xin = 12.0 MHz

SSCLK1 = 48.0 MHz

S1, S0 = 0

FRSEL = 1

P/N = CY25814

Xin = 24.0 MHz

SSCLK1 = 96.0 MHz

S1, S0 = 0

FRSEL = M

P/N = CY25814
