WebIn short, “Jitter is defined as the failure of Clock Generating Source to produce a Clean Edge Clock Cycle”. For example, a Clock Oscillator generates a Clock with 100 MHZ frequency so the clock period is 10ns means the consecutive edges will be 0ns 10ns 20ns 30ns, and so on for an ideal clock source. But, due to noise or issues, the clock ... WebNov 20, 2024 · The root or source of the clock tree in this example is a low jitter XO which determines the frequency stability of the clock tree overall. The clock generator then scales the input frequency from the XO to several different (usually higher) output frequencies. Finally, the clock buffer takes one of these output frequencies and yields multiple ...

Effects of Skew and Jitter on Clock Tree Design

WebAug 4, 2015 · This is called clock jitter which can be contributed from PLL or crystal osillator, cables, transmitters, receivers, internal circuitry of the PLL, thermal noise of the osillator … WebApr 14, 2013 · Clock jitter could also be defined as the crosstalk effect on the clock nets. Since a clock tree is used, different clock branches can have different crosstalk and therefore different jitter. Therefore this effect needs to be modeled or uncertainty introduced to add enough margin. How is the clock jitter handled in the design?
