FRACTIONAL-N RF/INTEGER-N IF DUAL PLL S1M8831A/33 INTRODUCTION The S1M8831A/33 is a Fractional-N frequency synthesizer with integrated prescalers, designed for RF operation up to 1.2GHz/K-PCS and for IF operation up to 520MHz.

The fractional-N synthesizer allows fast-locking, low phase noise phase-locked loops to be built easily, thus having rapid channel switching and reducing standby time for extended battery life.

The S1M8831A/33 based on ∑ - ∆ fractional-N techniques solves the fractional
