with Spread Spectrum

Quad PLL Programmable Clock Generator with Spread Spectrum

■ Up to nine clock outputs with programmable drive strength

■ Glitch free outputs while frequency switching

Features

■ Four fully integrated phase locked loops (PLLs)

■ 24-pin QFN package

■ Input frequency range

■ Commercial and Industrial temperature ranges

❐ External crystal: 8 to 48 MHz for CY2544 and CY2546

❐ External reference: 8 to 166 MHz clock

Benefits

■ Reference clock input voltage range

❐ 2.5 V, 3.0 V, and 3.3 V for CY2548

❐ 1.8 V for CY2544 and CY2546

■ 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

■ 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 CY2544 and CY2548

❐ 1.8 V for CY2546

■ Programmable PLLs for system frequency margin tests

■ Meets critical timing requirements in complex system designs

■ Selectable output clock voltages:

❐ 2.5 V, 3.0 V, and 3.3 V for CY2544 and CY2548

❐ 1.8 V for CY2546

■ Suitability for PC, consumer, portable, and networking

applications

■ Capable of Zero PPM frequency synthesis error

■ Frequency select feature with option to select eight different

frequencies over nine clock outputs

■ Uninterrupted system operation during clock frequency switch

■ Application compatibility in standard and low power systems

■ Power down, output enable, and SS ON/OFF controls

■ Low jitter, high accuracy outputs

Functional Description

■ Abilitytosynthesizenonstandard frequencies with Fractional-N

capability
