WebCrystal aging tends to be logarithmic, meaning the maximum rate of change of frequency occurs immediately after manufacture and decays thereafter. Most of the aging will occur within the first year of the crystal's service life. Crystals do eventually stop aging ( asymptotically ), but it can take many years. http://www.mti-milliren.com/MTIPapers/Ext_Aging_Perf_Results.pdf
Causes of Crystal Aging in Oscillators - CTS Corp
WebAging is the change in frequency of the oscillator over time under constant environmental and system-level conditions. Aging in quartz crystal oscillators is caused by changes in either the quartz crystal itself or the remaining components in the oscillator assembly. Aging in quartz crystals is the result of a combination of several factors. WebJun 3, 2024 · The general 'guide rule' is crystal aging of ±10ppm max over 10 years, although the crystal decays usually much less in reality.
