Description Crystal, ceramic resonator or clock input pin.
Functional Description
The CY25811/12/14 products are Spread Spectrum Clock Generator (SSCG) ICs used for the purpose of reducing electromagnetic interference (EMI) found in today's high-speed digital electronic systems. The devices use a Cypress proprietary phase-locked loop (PLL) and Spread Spectrum Clock (SSC) technology to synthesize and modulate the frequency of the input clock. By frequency modulating the clock, the measured EMI at the fundamental and harmonic frequencies is greatly reduced. This reduction in radiated energy can significantly reduce the cost of complying with regulatory agency requirements and improve time to market without degrading system performance. The input frequency range is 4 to 32 MHz and accepts clock, crystal and ceramic resonator inputs. The output clock can be selected to produce 1x, 2x, or 4x multiplication of the input frequency with Spread Spectrum Frequency Modulation. The use of 2x or 4x frequency multiplication eliminates the need for higher order crystals and enables the user to generate up to 128-MHz Spread Spectrum Clock (SSC) by using only first order crystals. This will reduce the cost while improving the system clock accuracy, performance and complexity. Center Spread or Down Spread frequency modulation can be selected by the user based on four discrete values of Table 2.

Input Frequency Range and Selection
The CY25811/12/14 input frequency range is 4 to 32 MHz. This range is divided into three segments and controlled by 3-Level FRSEL pin as given in Table 1. Table 1. Input Frequency Selection FRSEL 0 1 M Input Frequency Range 4.0 to 8.0 MHz 8.0 to 16.0 MHz 16.0 to 32.0 MHz
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 2.

3-Level Digital Inputs
S0, S1, and FRSEL digital inputs are designed to sense 3 different logic levels designated as High "1", Low "0" and Middle "M". With this 3-Level digital input logic, the 3-Level Logic is able to detect 9 different logic states. S0, S1 and FRSEL pins include an on chip 20K (10K/10K) resistor divider. No external application resistors are needed to implement the 3-Level logic levels as shown below: Logic Level "0": 3-Level logic pin connected to GND. Logic Level "M": 3-Level logic pin left floating (no connection). Logic Level "1": 3-Level logic pin connected to VDD. Figure 1 illustrates how to implement 3-Level Logic.

Modulation Rate
Spread Spectrum Clock Generators utilize frequency modulation (FM) to distribute energy over a specific band of frequencies. The maximum frequency of the clock (fmax) and minimum frequency of the clock (fmin) determine this band of frequencies. The time required to transition from fmin to fmax and back to fmin is the period of the Modulation Rate. The Modulation Rate of SSCG clocks are generally referred to in terms of frequency, or fmod = 1/Tmod. The input clock frequency, fin, and the internal divider determine the Modulation Rate. In the case of CY25811/2/4 devices, the (Spread Spectrum) modulation Rate, fmod, is given by the following formula: fmod = fin/DR where; fmod is the Modulation Rate, fin is the Input Frequency and DR is the Divider Ratio as given in Table 3. Notice that Input Frequency Range is set by FRSEL.

Input and Output Frequency Selection
The relationship between input frequency versus output frequency in terms of device selection and FRSEL setting is given in Table 4. 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 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.
