Pin Diagram General Description The CY25200 is a Spread Spectrum Clock Generator (SSCG) IC used to reduce Electro Magnetic Interference (EMI) found in today’s high speed digital electronic systems. The device uses 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 are greatly reduced. This reduction in radiated energy significantly reduces the cost of complying with regulatory agency requirements (EMC) and improves time to market, without degrading system performance. The CY25200 uses a factory and field-programmable configuration memory array to synthesize output frequency, spread %, crystal load capacitor, clock control pins, PD#, and OE options. The spread % is factory and field-programmed to either center spread or down spread with various spread percentages. The range for center spread is from ±0.25% to ±2.50%. The range for down spread is from –0.5% to –5.0%. Contact the factory for smaller or larger spread % amounts, if required. The input to the CY25200 is either a crystal or a clock signal. The input frequency range for crystals is 8–30 MHz and for clock signals is 8–166 MHz. The CY25200 has six clock outputs, SSCLK1 to SSCLK6. The frequency modulated SSCLK outputs are programmed from 3–200 MHz. The CY25200 products are available in a 16-pin TSSOP package with a commercial operating temperature range of 0 to 70°C. Table 1.

The CY25200 is Flash technology based, so the parts are reprogrammed up to 100 times. This allows for fast and easy design changes and product updates, and eliminates any issues with old and out of date inventory. Samples and small prototype quantities are programmed on the CY3672 programmer with the CY3695 socket adapter. CyberClocks™ Online Software CyberClocks™ Online Software is a web based software application that allows the user to custom configure the CY25200. All the parameters in given as “Enter Data” are programmed into the CY25200. CyberClocks Online outputs an industry standard JEDEC file used for programming the CY25200. CyberClocks Online is available at www.cyberclocksonline.com website through user registration. To register, fill out the registration form Document #: 38-07633 Rev. *E and make sure to check the “non-standard devices” box. For more information on the registration process refer to the CY3672 data sheet. For information regarding Spread Spectrum software programming solutions, please contact your local Cypress Sales or Field Application Engineer (FAE), representative for details. Factory-Programmable CY25200 Factory programming is available for volume manufacturing by Cypress. All requests must be submitted to the local Cypress Field Application Engineer (FAE) or sales representative. The sample request form provided by the representative must be completed. When the request is processed, you receive a new part number, samples, and data sheet with the programmed values. This part number is used for additional sample requests and production orders. Additional information on the CY25200 are available on the Cypress website at www.cypress.com. Page 3 of 11 [+] Feedback CY25200 Product Functions Control Pins (CP0, CP1, CP2 and CP3) There are four control signals available through programming of pins 4, 10, 14, and 15. CP0 (pin 4) and CP1 (pin10) are specifically designed to function as control pins. However pins 14 (SSCLK5/REFOUT/CP2) and 15 (SSCLK6/REFOUT/CP3) are multi-functional and are programmed to be a control signal or an output clock (SSCLK or REFOUT). All of the control pins, CP0, CP1, CP2, and CP3 are programmable and are programmed to have only one of the following functions: ■ Output Enable (OE)—if OE = 1, all the SSCLK or REFOUT outputs are enabled. ■ SSON, Spread spectrum control—1 = spread on and 0 = spread off. ■ CLKSEL—SSCLK output frequency select ■ PD#, Active Low—if PD# = 0, all the outputs are three-stated and the part enters a low power state. The last control signal is the power down (PD#) that is implemented only through programming CP0 or CP1 (CP2 and CP3 cannot be programmed as PD#). Here is an example with three control pins: ■ CLKIN = 33 MHz ■ SSCLK1/2/3/4 = 100 MHz with ±1% spread ■ SSCLK 5 = REFOUT(33 MHz) ■ CP0 (Pin 4) = PD# ■ CP1 (Pin 10) = OE ■ CP3 (pin 15) = SSON VCO frequency range is 100–400MHz. The CY25200 has two separate dividers, Divider 1 and Divider 2. These two are loaded to have any number between 2 and 130 providing two different but related frequencies as explained above. In the above example SSCLK5 (pin 14) and SSCLK6 (pin 15) are used as output clocks. However, they can also be used as control signals. See Figure 3 on page 5 for the pinout. Input Frequency (XIN, pin 1 and XOUT, pin 16) The input to the CY25200 is a crystal or a clock. The input frequency range for crystals is 8 to 30 MHz, and for clock signal is 8 to 166 MHz. CXIN and CXOUT (pin 1 and pin 16) The load capacitors at pin 1 (CXIN) and pin 16 (CXOUT) are programmed from 12 pF to 60 pF with 0.5 pF increments. The programmed value of these on-chip crystal load capacitors are the same (XIN = XOUT = 12 to 60 pF). The required values of CXIN and CXOUT for matching crystal load (CL) is calculated using the following formula: CXIN = CXOUT = 2CL – CP Where CL is the crystal load capacitor as specified by the crystal manufacturer and CP is the parasitic PCB capacitance. For example, if a fundamental 16 MHz crystal with CL of 16 pF is used and CP is 2 pF, CXIN and CXOUT is calculated as: CXIN = CXOUT = (2 x 16) – 2 = 30 pF. If using a driven reference clock, set CXIN and CXOUT to the minimum value 12 pF. Output Frequency (SSCLK1 through SSCLK6 Outputs) The pinout for the above example is shown in Figure 2. Figure 2. Pin Diagram 33.0MHz VDD 1 16 NC 2 15 AVDD 3 14 SSON REFOUT(33.0MHz) PD# 4 13 VSS AVSS 5 12 100MHz VSSL 6 11 VDDL 100MHz 7 10 OE 100MHz 8 9 100MHz The CLKSEL control pin enables the user to change the output frequency from one frequency to another (for example, frequency A to frequency B). These must be related frequencies that are derived off of a common VCO frequency. For instance, 33.333 MHz and 66.666 MHz are both derived from a VCO of 400 MHz and dividing it down by 12 and 6 respectively. Table 4 on page 5 shows an example of how this is implemented. The Document #: 38-07633 Rev. *E All of the SSCLK outputs are produced by synthesizing the input reference frequency using a PLL and modulating the VCO frequency. SSCLK[1:4] is programmed to be only output clocks (SSCLK). SSCLK5 and SSCLK6 are also programmed to function the same as SSCLK[1:4] or a buffered copy of the input reference (REFOUT) or they are programmed to be a control pin as discussed in the control pins section. To use the 2.5V output drive option on SSCLK[1:4], VDDL must be connected to a 2.5V power supply (SSCLK[1:4] outputs are powered by VDDL). When using the 2.5V output drive option, the maximum output frequency on SSCLK[1:4] is 166 MHz. Spread Percentage (SSCLK1 through SSCLK6 Outputs) The SSCLK frequency is programmed at any percentage value from ±0.25% to ±2.5% for center spread and from –0.5% to –5.0% down spread. Frequency Modulation The frequency modulation is programmed at 31.5 kHz for all SSCLK frequencies from 3 to 200 MHz. Contact the factory if a higher modulation frequency is required.
