Essentially, timing jitter is the deviation of an oscillator’s edge from its ideal location. As an oscillator’s signal gets multiplied and filtered, the jitter gets multiplied and filtered as well, and a system’s timing budget can quickly disappear.

2022年3月4日 · Period measures the time between the closest edges with the same slope. The TIE parameter measures the time difference on a data edge from its ideal position. TIE can be thought of as reporting the instantaneous phase of the data stream. TIE requires a knowledge of the data stream’s clock rate.

Phase Noise and Jitter are important metrics that describe the quality of a low-noise oscillator. Jitter is a time-domain representation of the timing accuracy of a signal and Phase Noise is the frequency domain representation of noise spectrum around the carrier tone.

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*.

Jitter is a time deviation of a signal transition from its ideal position in time. It can be caused by many different factors, including PLL loop noise, thermal noise, cross talk, power supply ripply. It can be characterized by using multiple terminology.

2023年3月27日 · TIE jitter is the variation of an edge with respect to a reference waveform edge. It is the short-term variation of the significant instances of a digital signal from its ideal position in time. TIE is the most complicated form of jitter between the three types.

Jitter is the timing variations of a set of signal edges from their ideal values. Jitters in clock signals are typically caused by noise or other disturbances in the system. Contributing factors include thermal noise, power supply variations, loading conditions, device noise, and interference coupled from nearby circuits. 2. Types of Jitter.

We consider an ideal clock that is being jittered (i.e., the clock’s edges experience movement with respect to ideal locations). The jitter of a particular waveform can be measured/characterized as period, cycle-to-cycle, or time interval error (TIE). Period 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.

2016年12月9日 · Timing error is known as jitter. A small amount can be tolerated, but jitter above a critical level will cause bit errors. Jitter that is bad enough can cause complete signal failure. Jitter can be defined in several ways. Absolute jitter. is the absolute difference in the position of a clock’s edge from where it would be ideally.
