Overview
The ADF4002BCPZ from Analog Devices Inc. is a high-performance frequency synthesizer designed to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and a programmable N divider. The device can be used to create a complete phase-locked loop (PLL) when combined with an external loop filter and voltage-controlled oscillator (VCO). Additionally, it can function as a standalone PFD and charge pump by programming R and N to 1.
