... Power-down function. For Automotive applications, refer to CY25811/12/14SE data sheets. Input Frequency Range and Selection The CY25811/12/14 input frequency range MHz. This range is divided into three segments and controlled by a 3-Level FRSEL pin as given in Table 2. Input Frequency Selection ...

... Spread% Selection The CY25811/12/14 SSCG products provide Center-Spread, Down-Spread and No-Spread functions. The amount of Spread% is selected by using 3-Level. S0 and S1 digital inputs and Spread% values are given in Table 3. Spread% Selection XIN FRSEL (MHz Center Center (%) (%) 4-5 0 ±1.4 ± 1.2 5-6 0 ±1.3 ± ...

... The relationship between input frequency versus output frequency in terms of device selection and FRSEL setting is given in As shown, the input frequency range is selected by FRSEL and is the same for CY25811, CY25812, and CY25814. The selection of CY25811 (1x), CY25812 (2x) or CY25814 (4x) determines the frequency multiplication at the output (SSCLK, Pin 5) with respect to input frequency (XIN, Pin-1) ...

... SSCG Profiles CY25811/12/14 SSCG products use a non-linear “optimized” frequency profile as shown In “optimized” frequency profile maintains flat energy distribution over the fundamental and higher order harmonics. This results in additional EMI reduction in electronic systems. Figure 4. Spread Spectrum Profiles (Frequency vs. Time) Xin = 6.0 MHz SSCLK1 = 6 ...
