CY25100  
Field- and Factory-Programmable Spread Spectrum  
Clock Generator for EMI Reduction  
Benefits  
Features  
• Wide operating output (SSCLK) frequency range  
— 3–200 MHz  
• Services most PC peripherals, networking, and consumer  
applications.  
• Provides wide range of spread percentages for maximum  
electromagnetic interference (EMI) reduction, to meet  
regulatory agency electromagnetic compliance (EMC)  
requirements. Reduces development and manufacturing  
costs and time-to-market.  
• Eliminates the need for expensive and difficult to use  
higher-order crystals.  
• Internal PLL to generate up to 200-MHz output. Able to  
generate custom frequencies from an external crystal or a  
driven source.  
• In-house programming of samples and prototype quantities  
is available using the CY3672 programming kit and  
CY3690(TSSOP) or CY3691(SOIC) socket adapter.  
Production quantities are available through Cypress’s  
value-added distribution partners or by using third party  
programmers from BP Microsystems, HiLo Systems, and  
others.  
• Programmable spread spectrum with nominal 31.5-kHz  
modulation frequency  
— Center spread: ±0.25% to ±2.5%  
— Down spread: –0.5% to –5.0%  
• Input frequency range  
— External crystal: 8–30 MHz fundamental crystals  
— External reference: 8–166 MHz Clock  
• Integrated phase-locked loop (PLL)  
• Field-programmable  
— CY25100SCF, 8-pin SOIC  
— CY25100ZCF, 8-pin TSSOP  
• Programmable crystal load capacitor tuning array  
• Low cycle-to-cycle Jitter  
• 3.3V operation  
• Spread Spectrum On/Off function  
• Power-down or Output Enable function  
• Enables fine-tuning of output clock frequency by adjusting  
C
Load of the crystal. Eliminates the need for external CLoad  
capacitors.  
• Suitable for most PC, consumer, and networking applica-  
tions  
• Application compatibility in standard and low-power  
systems.  
• Provides ability to enable or disable spread spectrum with  
an external pin.  
• Enables low-power state or output clocks to High-Z state.
