Overview
The ADF4150BCPZ from Analog Devices Inc. is a fractional-N or integer-N phase-locked loop (PLL) frequency synthesizer. This device is designed to be used with an external voltage-controlled oscillator (VCO), loop filter, and external reference frequency. It is software compatible with the ADF4350 and allows for the generation of RF output frequencies as low as 31.25 MHz by dividing the VCO frequency by 1, 2, 4, 8, or 16. The ADF4150BCPZ features a simple 3-wire serial interface for controlling all on-chip registers and includes functionalities such as RF output mute, analog and digital lock detect, and switched bandwidth fast-lock mode for cycle slip reduction.
