Being a long time employee of a major player in the so-called “Clocks & Timing” semiconductor industry, (i.e. a manufacturer of electronic chips which create low-jitter clocks), I am interested to know more about the jitter values we see on Auralic products’ pages, such as:
- Altair, 120 fs
- Vega G2, 72 fs
- LEO, as a specialized clock generator, should be even better.
How are these numbers measured? Which definition of jitter do they refer to? (period jitter, cycle-to-cycle, RMS phase jitter etc?)
For all of you interested to know more about jitter, I find this application note by SiLabs very informative and well written:
Please note that this question comes purely out of personal curiosity, no business purpose or connection with my employer (or any other manufacturer in the industry) is meant or intended by any means here.
