Overview
FRACTIONAL-N RF/INTEGER-N IF DUAL PLL
S1M8836/37
INTRODUCTION
The S1M8836/37 is a Fractional-N frequency synthesizer with integrated prescalers, designed for RF operation up to 1.
0GHz/2.
5GHz 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 S1M8836/37 based on Σ - ∆ 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 PCS/CDMA channel frequency in steps of 10kHz can be accurately...
