CY25100  
Field and Factory-Programmable Spread Spectrum  
Clock Generator for EMI Reduction  
Features  
Benefits  
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) require-  
ments. Reduces development and manufacturing costs and  
time-to-market.  
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  
Eliminates the need for expensive and difficult to use  
higher-order crystals.  
InternalPLLtogenerateupto200MHzoutput.Abletogenerate  
custom frequencies from an external crystal or a driven source.  
Integrated phase-locked loop (PLL)  
Field-programmable  
CY25100SCF and CY25100SIF, 8-pin SOIC  
CY25100ZCF and CY25100ZIF, 8-pin TSSOP  
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 crystal load capacitor tuning array  
Low cycle-to-cycle jitter  
3.3V operation  
Enables fine-tuning of output clock frequency by adjusting  
Commercial and Industrial operation  
Spread Spectrum On/Off function  
Power down or Output Enable function  
CLoad of the crystal. Eliminates the need for external CLoad  
capacitors.  
Suitable for most PC, consumer, and networking applications  
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.
