Timing jitter is the fluctuation in pulse positions, with mode-locked lasers achieving low jitter over short timescales.

In clock recovery applications it is called timing jitter. [1] Jitter is a significant, and usually undesired, factor in the design of almost all communications links. Jitter can be quantified in the same terms as all time-varying signals, e.g., root mean square (RMS), or …

but conceptually, jitter is the deviation of timing edges from their “correct” locations. In a timing-based system, timing jitter is the most obvious and direct form of non-idealness. As a form of noise, jitter must be treated as a random process and characterized in terms of its statistics.

overview of the approaches used to specify and measure jitter in timing devices. What is Jitter? Jitter as defined by NIST is the “short term phase variation of the significant instants of a digital signal from their ideal positions in time”. Essentially, timing jitter is the deviation of an oscillator’s edge from its ideal location.

Timing jitter is a fundamental challenge in photonic systems, but it can be effectively mitigated through a combination of detector optimization, signal processing techniques, and stable optical path management.

Timing jitter is the unwelcome companion of all electrical systems that use voltage transitions to represent timing information. Historically, electrical systems have lessened the ill effects of timing jitter (or, simply “jitter”) by employing relatively low signaling rates.

Abstract: A simple method for the estimation of timing jitter in ultrafast lasers is presented and applied for the first time to the characterization of ultralong passively mode-locked femtosecond fiber oscillators with ultra-low repetition rates in the range of kHz.

Jitter is the measure of timing performance. High jitter means poor timing performance in most cases. This primer provides an overview of jitter and offers practical assistance in taking jitter measurements. Jitter falls into two broad categories: random jitter and deterministic jitter*.

Moreover, a pulse-to-pulse timing jitter of 2.1 fs and integrated timing jitter of 564.8 fs in the frequency range from 35 kHz to 20 MHz are obtained. It is observed that the 1/f 2 white flicker frequency is the main contribution to the phase noise in the low frequency (<250 kHz), and shot noise dominants when frequency is >250 kHz.
