Overview
The ADF4351BCPZ is a phase-locked loop (PLL) frequency synthesizer integrated circuit produced by Analog Devices Inc. This device is designed to support a wide range of frequency synthesis applications, particularly in wireless infrastructure, test equipment, and other RF systems. It features an integrated voltage-controlled oscillator (VCO) with a fundamental output frequency range of 2200 MHz to 4400 MHz. The ADF4351BCPZ also includes divide-by-1/-2/-4/-8/-16/-32/-64 circuits, allowing for the generation of RF output frequencies as low as 35 MHz. The device operates with a power supply range of 3.0 V to 3.6 V and is packaged in a 32-lead lead frame chip scale package (LFCSP).
