X MCLK jitter: The DAC code and, hence, IDAC change every clock time period Ts. If the IDAC time period randomly changes, then the average integrated value keeps changing, as shown in Figure 13. So, any error in the sampling clock time period in the form of jitter would affect the ...
Interestingly, the extremes average out more and more as the sample data increases. Thus, TDEV becomes a highly averaged value. And if the noise in the clock is occurring rarely, the degree (or magnitude) of this rarely occurring error starts diminishing over longer periods of measurement. An...
SHA aperture jitter generally is less than 50 ps rms and less than 5 ps rms in high-speed devices. Figure 3-18 shows the effects of total sampling clock jitter on the signal- to-noise ratio of a sampled data system. The total rms jitter will be composed of a number of components, ...
Multiple runs may also be used to average the values providing more accurate results. Actual distance measurements are dependent on the velocity of propagation of the cable. The delay value is typically on the order of 4.6 to 4.9 ns/m. 5.3.9 BIST The DP83640 incorporates an internal Built-...

While cycle to cycle is used for spread spectrum clocks rather than period jitter, it is relevant to measure the contribution of the clock to the system accuracy. 2.3.3.2.5 Long-Term Jitter Long-term jitter though is not defined in JESD65B; however, it is often mentioned in literature for...
The estimate of the interarrival jitter (J) is computed continuously as each RTP data packet is received from the N th synchronization source and sampled whenever a report is issued. The last sender report time stamp (LSR) field provides the NTPT received in the most recent RTCP SR packet ...

Generally, we hope the initial offset in the first period of each flow will repeat in the following periods like TTE; however, because preemption is inevitable and unpredictable, the delay and jitter of the preempted parts will be out of control. Therefore, we propose flow-based deterministic ...
