Overview
Data Sheet FEATURES Fractional-N/Integer-N PLL Synthesizer ADF4151 GENERAL DESCRIPTION The ADF4151 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers if used with an external voltage controlled oscillator (VCO), loop filter, and external reference frequency.
The ADF4151 is used with external VCO parts and is footprint and software compatible with the ADF4350.
The part consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider.
There is a Σ-Δ based fractional interpolator to allow programmable fractional-N division.
The INT, FRAC, and MOD registers define an overall N divider [N ...
