GENERAL DESCRIPTION
The ADF4002 frequency synthesizer is used to implement local
oscillators in the upconversion and downconversion sections of
wireless receivers and transmitters. It consists of a low-noise
digital phase frequency detector (PFD), a precision charge
pump, a programmable reference divider, and programmable
N divider. The 14-bit reference counter (R counter), allows
selectable REFIN frequencies at the PFD input. A complete
phase-locked loop (PLL) can be implemented if the synthesizer
is used with an external loop filter and voltage controlled
oscillator (VCO). In addition, by programming R and N to 1,
the part can be used as a stand alone PFD and charge pump.
