Overview

The ADF4351BCPZ-RL7 is a wideband fractional-N and integer-N phase-locked loop (PLL) frequency synthesizer with an integrated voltage controlled oscillator (VCO). It operates across a frequency range of 35 MHz to 4.4 GHz, utilizing a series of internal dividers to provide a high-performance clock output.

Why Choose This Part

It offers exceptional frequency flexibility by combining a wideband VCO with programmable output dividers. The device supports 3.0V to 3.6V operation and features a low-noise floor, making it ideal for systems that require high spectral purity across a broad range of frequencies.

Applications

Wireless Infrastructure
Used as a local oscillator for base stations and cellular backhaul equipment requiring wide frequency coverage.
Test and Measurement
Integrated into signal generators and spectrum analyzers for flexible frequency synthesis up to 4.4 GHz.
Satellite Communications
Provides stable frequency generation for VSAT and satellite ground terminal equipment.
Clock Distribution
Functions as a high-frequency fanout buffer and clock generator for high-speed digital systems.
