ADF4002BRUZ

The ADF4002BRUZ is a frequency synthesizer from Analog Devices designed for local oscillator generation in wireless transceivers. It integrates a low-noise digital phase frequency detector (PFD), precision charge pump, programmable reference divider, and programmable N divider. With a maximum operating frequency of 400 MHz and a phase detector frequency of 104 MHz, it supports a wide range of clock conditioning and generation applications.

The device operates from a 2.7V to 3.3V supply and features a separate charge pump supply (VP) for extended tuning voltage in 3V systems. It includes a 3-wire serial interface, analog and digital lock detect, and hardware/software power-down mode. The ADF4002BRUZ can be used as a complete phase-locked loop (PLL) when combined with an external loop filter and VCO, or as a standalone PFD and charge pump by programming R and N counters to 1.

Packaged in a 16-TSSOP (0.173" width, 4.40mm) surface mount package, the ADF4002BRUZ is suitable for space-constrained designs. It operates over a temperature range of -40°C to 85°C, making it reliable for industrial and commercial environments. Typical applications include clock conditioning, clock generation, and IF LO generation in wireless systems.
