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 spur problems in other fractional-N synthesizers based on charge pump compensation. The synthesizer also has an additional feature that the www.DataSheet4U.com PCS/CDMA channel frequency in steps of 10kHz can be accurately programmed. 24-QFN-3.5×4.
