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? WebNov 20, 2024 · In such applications, we need to add a jitter attenuator to clean up the source clock noise and improve the clock tree jitter performance. The figure below …

WebJul 10, 2024 · One such factor is clock jitter. Fluctuation of the clock edge from its ideal position is termed as clock jitter. For example, a clock period of 1ns having 50% duty cycle should have first rising edge at 0ps, first falling edge at 500ps and second rising edge at 1ns. Deviation of rising/falling edge from its ideal time period is called jitter. haveri karnataka 581110WebWith a wide portfolio of buffer products, fixed-function differential and CMOS, universal clock buffers, as well as automotive grade buffers, our universal clock buffers support any in/out signal format and integrate both clock mixing and division to further simplify clock tree design.
