ADF5001BCPZ

ADF5001BCPZ is Analog Devices’ ADF5001 fractional-N phase-locked loop (PLL) frequency synthesizer in the BCPZ package. It’s designed to generate precise RF carrier frequencies for wireless, radar, and test/measurement applications with minimal external components. Key ideas: a PLL with an integrated or externally aided VCO path, digital delta-sigma fractional-N modulation, and programmable reference/divider/modulus options that allow fine frequency steps and low spurious performance. It supports integer and fractional-N operation, fast lock times, and is controllable via a serial interface (SPI) for setting frequencies, dividers, and modulus values. Typical external needed parts include a reference input, loop-filter components, and RF output matching/network. For exact electrical specs, integration details, and the specific package drawings of the BC(P)Z variant, refer to the ADF5001 datasheet and packaging document.
