Features

■ Integrated phase-locked loop (PLL)

■ Low jitter, high-accuracy outputs

■ 3.3V operation

■ 25-MHz input frequency

■ 66.66-MHz or 33.33-MHz selectable output frequency (orig,

-3,-11,-31)

■ 33.33-MHz or 25-MHz selectable output frequency (-2,-21)

Benefits

■ High-performance PLL tailored for Spread Spectrum appli-

cation

■ Meets critical timing requirements in complex system designs

■ Enables application compatibility

■ Works with commonly available crystal or driven reference

■ Downspread Spread Spectrum with 30-kHz nominal

modulation frequency
