SNR versus clock amplitude versus input frequency (from ADS54RF63 data sheet) on...
Incorporated Data Acquisition Clock jitter analyzed in the time domain, Part 2 By Thomas Neu Systems and Applications Engineer Introduction Part 1 of this three-part article series focused on how to accurately estimate jitter from a clock source and combine it with the aperture jitter of an ADC....
In addition to such dedicated requirements, low jitter, small power and area are the fundamental design goals to improve the competitiveness of the overall SoC solutions. The successive and consistent architecture iterations in the past decades have continuously pushed the overall performance envelope ...
time-division multiplexed (OTDM) systems, where the line-rate clock isntimes of the base rate withnbeing the number of TDM channels. InReference 20, a base-rate clock recovery technique is analyzed and demonstrated. In the proposed scheme, an electrical clock is extracted from an ultra-high-...
but jitter is yet another variability or unknown that narrows the time you have to do work, because the clock may be late or early. It’s random. It’s statistical the ways it jitters, so it impacts the entire chip’s timing. If you can reduce the jitter by, let’s say, 10%, or...
the PSMR results for each supply rail, LDO noise characteristics, and the DAC setup, the noise contributions from each source can be calculated and optimized. An example budget is shown in Figure 22. With all sources properly considered, phase noise can b...
Clock skew in high frequency clock domains (+300 MHz) can impact performance. In general, the clock skew should be no more than 500 ps. For example, 500 ps represents 15% of a 300 MHz clock period, which is equivalent to the timing budget of 1 or 2 logic levels. In clock domain-cr...
The dynamic behavior of three section DFB self-pulsating lasers, used as clock recovery device, is theoretically analyzed using a time domain traveling wave simulator. The effect of the bias operating conditions on the self-pulsation frequency is discussed through both static and dynamic analysis. ...
