Phase Noise of Integer-N and Fractional-N PLL Synthesizers

Kevin B. Scott - Senior Strategic Marketing Engineer
Michel Azarian - Product Marketing Engineer Feb 10th 2015
Phase Noise of Integer-N and Fractional-N PLL Synthesizers Low phase noise is essential when generating high frequency, high linearity signal sources. Phase noise is a measure of the undesirable change or variation in phase of a signal. It is measured in the frequency domain and equates to jitter in the time domain. When using ...

Low Phase Noise Frequency Synthesizers for RF Applications

Doug LaPorte - Design Manager Sep 19th 2011
In modern RF communication systems, signal integrity is of prime importance. To meet the system requirements, amplifiers, mixers and modulators must have a low noise figure and low distortion products. Additionally, as system designers work to squeeze increasingly more data into the available bandwidth, low phase noise signal ...
