ADF4351
Overview
The Analog Devices ADF4351 is a wideband voltage-controlled oscillator (VCO) and phase-locked loop (PLL) frequency synthesizer capable of generating RF signals from 35 MHz to 4.4 GHz. It integrates a fractional-N or integer-N PLL synthesizer, allowing for high-resolution frequency generation and excellent phase noise performance. This device is suitable for applications requiring stable and precise RF signal sources.
Why Choose This Part
Engineers choose the ADF4351 for its wide operating frequency range up to 4.4 GHz and its flexible fractional-N or integer-N synthesis capabilities. The integrated low phase noise VCO and programmable output divider simplify design by reducing external component count. Its 3-wire serial interface provides easy programmability for frequency and output power control.
Applications
Key Specifications
Getting Started
To get started with the ADF4351, Analog Devices offers evaluation boards (e.g., EVAL-ADF4351EBZ) that include the necessary support circuitry and SMA connectors for RF input/output. These boards typically interface with a PC via USB, allowing control through software provided by Analog Devices. The software facilitates configuration of the PLL parameters, frequency output, and output power.
