Overview
The ADF4350BCPZ, produced by Analog Devices Inc., is a highly versatile phase-locked loop (PLL) frequency synthesizer. This device is designed to support both fractional-N and integer-N PLL configurations, making it suitable for a wide range of applications. It features an integrated voltage-controlled oscillator (VCO) with a fundamental output frequency range of 2200 MHz to 4400 MHz. Additionally, the device includes divide-by-1/2/4/8 or 16 circuits, allowing for the generation of RF output frequencies as low as 137.5 MHz. The ADF4350BCPZ is controlled via a simple 3-wire serial interface and operates with a power supply ranging from 3.0 V to 3.6 V, making it energy-efficient and easy to integrate into various systems.
