What is jitter? Jitter is the time distortions of recording/playback of a digital audio signal. Many audiophile digital audio system owners worries about jitter. Below we will discuss why jitter exists, who it is estimated, and suppressed. Digital-analog converters (DAC) transform sample sequences (digital values) to analog voltage level sequences.

What is jitter audio Digital-analog converter (DAC) transforms sample sequence (digital values) to analog voltage level sequence. In the ideal case, the same time distance between the samples should be provided. The distance is defined by clock. However, clocking is not ideal and the restored signal is distorted like it is shown in the picture.

Jitter is expressed in RMS microseconds. So when we say there is a 2µs RMS jitter, it means the clock was, on average, off by 2µs. 1kHz Let's start with a 1kHz sinusoidal wave. 1kHz v1 Your browser does not support the audio element. 1kHz v2 Your browser does not support the audio element. 1kHz v3 Your browser does not support the audio element.
Jitter spectrum measurement with a low cost DSO

At higher jitter frequencies (> 2 kHz) when measuring typical bit clocks (i.e. 3 MHz to 24 – MHz) the measurement jitter noise floor is around 20 psec RMS. For lower frequencies it’s around 200 psec RMS due to the need for longer record lengths. For more details read the app note. The software and example files are found in the .zip file.
Analyzing Audio DAC Jitter Sensitivity - Maxim Integrated

There currently is no standard methodology for evaluating jitter tolerance. The Audio Precision 2700 (AP2700) audio analyzer can create a jittered clock, but it creates mostly low-frequency jitter (mostly below the Nyquist audio sample rate) as shown in Figure 1. Figure 1. Spectrum of 5ns "wideband" jitter generated from an AP2700.

Low-frequency jitter spectrum for a cycle-skipped clock. Several Maxim parts, including audio codecs ( MAX98089 and MAX98096) and the MAX98355 / MAX98356 power amplifiers, benefit from a highly jitter-tolerant DAC. The devices are specified to tolerate up to 0.5ns of jitter in the 0 to 40kHz band and 12ns of jitter above 40kHz.

Jitter can cause annoying flicker in computer monitors as well as clicks in audio output and garbled data in digital networks. Like phase noise, jitter can be viewed as spectral density in a spectrum analyzer. It is measured in root-mean-square (RMS) or peak-to-peak values.
