The model number is a specific version of a generic that can be purchased or sampled. Status Status indicates the current lifecycle of the product.

This can be one of 4 stages: The model has not been released to general production, but samples may be available. The model is currently being produced, and generally available for purchase and sampling. The model has been scheduled for obsolescence, but may still be purchased for a limited time.

The specific part is obsolete and no longer available. Other models listed in the table may still be available if they have a status that is not obsolete.

Package Description The package for this IC i.

Poly-Phase Fractional-N Frequency Synthesizer Andrey Martchovsky June Abstract The aim of this thesis is to present a phase-hopping frequency synthe-. Fractional-N synthesizers work by periodically changing the division ratio from N to N+1 and back such that the average is N + F/M where 0≤F. The common approach to frequency synthesis design for wireless communication is to design an analog-compensated fractional-N phase-locked loop (PLL). However, this technique suffers from lock time limitations, and inadequate fractional spur suppression, and falls short of third generation wireless standards.

An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. For detailed drawings and chemical composition please consult our Package Site.

The thesis presents simulation and experimental investigation of mechanisms for spur generation in a fractional-N frequency synthesizer. Simulations are carried out using the CppSim system simulator, MATLAB and Simulink while the experiments are performed on an Analog Devices ADF, a high performance narrow-band transceiver IC.
