IEEE Std 2414-2020 pdf download – IEEE Standard Jitter and Phase Noise.
cycle-to-cycle jitter (C2C): The difference between consecutive period durations in an ideally periodic signal. data-dependent jitter (DDJ): The contribution to the deterministic jitter in a two-level (binary) or multilevel signal, typically referenced to the transitions among the states of the signal. deterministic jitter (DJ): The contribution to the jitter in which successive reference instants are deterministically predicted. duty cycle distortion (DCD): The variable delay between the positive-going and the negative-going reference level transitions between cycles of the signal of interest. event: Any feature in a waveform whose instant of occurrence is uniquely defined. frequency drift rate: A measure of the time rate of change of the frequency offset (i.e. frequency stability). frequency offset: A measure of the difference between the observed clock frequency and its ideal value. instant: A particular time value within a waveform epoch that, unless otherwise specified, is referenced relative to the initial instant of that waveform epoch. jitter: The deviation of a sequence of reference instants from their ideal values. NOTE—The reference level instant used in this standard is the user-defined reference instant epoch. maximum time interval error (MTIE): The maximum TIE (in magnitude) within a user-defined observation interval. peak-to-peak jitter: The difference between the maximum and the minimum values of either the TE or the TIE. periodic jitter (PJ): The periodic contribution to the deterministic jitter in a two-level (binary) or multilevel signal, typically referenced to the transitions among the states of the signal. period jitter (PEJ): The jitter in the period of a repetitive signal or its waveform.
3. Jitter models and figures of merit 3.1 General concepts Jitter is a general term that describes a phenomenon consisting in the deviation of the reference instants of a sequence of events from their ideal values. Jitter may be interpreted in several ways, as will be discussed in this standard, depending on the practical effect of interest and its application. Jitter has many different physical sources. However, from a behavioral point of view, jitter can be modeled by means of statistical distributions, time trends, and frequency domain analysis of event reference instant deviations. Jitter appears either on ideally periodic signals, like those generated by clock sources and sine wave generators; inherently non-periodic signals, like baseband digital signals; or in general repetitive signals that include asynchronous events. It is the features and instants in a waveform that are amenable to measurement and analysis and, hence, the reference to waveform characteristics in this standard. The word “actual” when it refers to a waveform or its features is used to indicate the measured or acquired waveform or its features.
