ADF4159WCCPZ

ADF4159WCCPZ is Analog Devices’ wideband fractional-N phase-locked loop (PLL) frequency synthesizer. It generates RF output frequencies by locking an external VCO to a precise reference clock through a programmable divider/modulus, enabling fine frequency steps with low phase noise and reduced spurs. The device is SPI-compatible and lets you program the reference divider, modulus, and fractional/N settings, as well as enable/lock-detect/power-down controls. It supports both integer- and fractional-N operation (with options to improve spur performance) and includes core PLL blocks (phase detector, charge pump) for versatile RF synthesis. The WCCPZ suffix denotes the package/temperature variant. Typical applications include wireless transceivers, radar, telecom infrastructure, and test equipment. For exact electrical specs, VCO ranges, and programming sequences, consult the ADF4159 datasheet and package documentation.
