Phase Detector/Frequency Synthesizer

ADF4002

FEATURES

GENERAL DESCRIPTION

400 MHz bandwidth

2.7 V to 3.3 V power supply

Separate charge pump supply (V_P) allows extended

tuning voltage in 3 V systems

Programmable charge pump currents

3-wire serial interface

Analog and digital lock detect

Hardware and software power-down mode

200 MHz phase detector

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.
