Overview
The ADF4002BCPZ-RL7 is a frequency synthesizer produced by Analog Devices Inc. It is designed to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. The device consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and a programmable N divider. This synthesizer allows for the implementation of a complete phase-locked loop (PLL) when used with an external loop filter and voltage-controlled oscillator (VCO). Additionally, it can be used as a standalone PFD and charge pump by programming the R and N counters to 1.
