AES 12id-2006 (R2017) PDF Download

The AES Information Document for Digital Audio Measurements - Jitter Performance Specifications, titled AES 12id-2006 (R2017), addresses the issue of sample-clock quality in digital audio equipment design. The document highlights the lack of information provided by chip makers regarding the jitter performance of their products, which often leaves equipment designers unprepared to deal with jitter-related issues.

With the increasing use of packet-based communications and class-D amplification, the importance of addressing jitter has become even more pronounced. The document aims to provide a comprehensive review of various methods for characterizing and quantifying jitter, while also refining these methods specifically for audio purposes. It also strives to establish a standardized and unambiguous terminology for discussing jitter performance.

The focus of the document includes topics such as wideband jitter, baseband jitter, jitter spectra, period jitter, long-term jitter, and jitter signatures. It also offers insights into jitter transfer through phase-locked loops and the susceptibility of audio converters to jitter. Ultimately, the document serves as a valuable resource for audio equipment designers looking to measure and address jitter performance in their designs.
