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 significantly reduces the cost of complying with regulatory agency requirements and improves 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 reduces the cost while improving the system clock accuracy, performance, and complexity. Document Number: 38-07112 Rev. *G The user selects Center Spread or Down Spread frequency modulation based on four discrete values of Spread % for each Spread mode with the option of a Non Spread mode for system test and verification purposes. The CY25811/12/14 products are available in an 8 pin SOIC -150 mil package with a commercial operating temperature range of 0 to 70C and Industrial Temperature range of -40 to 85C. Refer to CY25568 for multiple clock output options such as modulated and unmodulated clock outputs or 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 is 4 to 32 MHz. This range is divided into three segments and controlled by a 3-Level FRSEL pin as given in Table 2.

With this 3-Level digital input logic, the 3-Level Logic detects nine different logic states. S0, S1, and FRSEL pins include an on chip 20K (10K and 10K) resistor divider. No external application resistors are needed to implement the 3-Level logic levels as shown here: SSCGs use 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: Logic Level "0": 3-Level logic pin connected to GND. fmod = 1/Tmod. Logic Level "M": 3-Level logic pin left floating (no connection). The input clock frequency, fin, and the internal divider determine the Modulation Rate. Logic Level "1": 3-Level logic pin connected to VDD. Figure 2 illustrates how to implement 3-Level Logic. In CY25811/2/4 devices, the (Spread Spectrum) modulation Rate, fmod, is given by the following formula: Figure 2. 3-Level Logic fmod = fin/DR LOGIC MIDDLE (M) LOGIC LOW (0) S0, S1 and FRSEL UNCONNECTED S0, S1 and FRSEL to VSS VSS Document Number: 38-07112 Rev. *G LOGIC HIGH (H) S0, S1 and FRSEL to VDD Here fmod is the Modulation Rate, fin is the Input Frequency, and DR is the Divider Ratio as given in Table 4.

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). Table 5.
