CY2545/CY2547  
Quad PLL Programmable Spread Spectrum  
Clock Generator with Serial I2C Interface  
Quad PLL Programmable Spread Spectrum Clock Generator with Serial I2  
C Interface  
■ Glitch-free outputs while frequency switching  
■ 24-pin QFN package  
Features  
■ Four fully integrated phase locked loops (PLLs)  
■ Commercial and industrial temperature ranges  
■ Input frequency range  
❐ External crystal: 8 to 48 MHz  
❐ External reference: 8 to 166 MHz clock  
Benefits  
■ Multiple high performance PLLs allow synthesis of unrelated  
frequencies  
■ Wide operating output frequency range  
❐ 3 to 166 MHz  
■ Nonvolatile programming for personalization of PLL  
frequencies, spread spectrum characteristics, drive strength,  
crystal load capacitance, and output frequencies  
■ Serial programmable over 2-wire I2C interface  
■ Programmable spread spectrum with center and down spread  
option and Lexmark and Linear modulation profiles  
■ Application specific programmable EMI reduction using Spread  
Spectrum for clocks  
■ VDD supply voltage options:  
❐ 2.5 V, 3.0 V, and 3.3 V for CY2545  
❐ 1.8 V for CY2547  
■ Programmable PLLs for system frequency margin tests  
■ Meets critical timing requirements in complex system designs  
■ Selectable output clock voltages independent of VDD supply:  
❐ 2.5 V, 3.0 V, and 3.3 V for CY2545  
❐ 1.8 V for CY2547  
■ Suitability for PC, consumer, portable, and networking  
applications  
■ Capable of zero PPM frequency synthesis error  
■ Power-down, output enable, or frequency select features  
■ Low jitter, high accuracy outputs  
■ Uninterrupted system operation during clock frequency switch  
■ Application compatibility in standard and low power systems  
■ Abilitytosynthesizenonstandard frequencies with Fractional-N  
capability  
Functional Description  
■ Up to eight clock outputs with programmable drive strength
