Overview

Data Sheet Phase Detector/Frequency Synthesizer ADF4002 FEATURES 400 MHz bandwidth 2.
7 V to 3.
3 V power supply Separate charge pump supply (VP) 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 104 MHz phase detector APPLICATIONS Clock conditioning Clock generation IF LO generation 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).
