Crystal aging per year
WebMost 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. Movement manufacturers can pre-age crystals before assembling them into clock movements. To promote accelerated aging the crystals are exposed to high temperatures.

WebTypical Temperature Stability: ±0.20 ppm to ±2.0 ppm. Typical aging rate: ±0.50 ppm/year to ±2 ppm/year. Temperature controlled crystal oscillators (TCXO) act similarly to OCXOs in … 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 7, 1996 · This paper reports on the results of pre-aging of four different types of OCXO crystal units. It compares the aging behaviour for a passive aging at +80/spl deg/C over 28 days and 12 days at different drive levels and the active aging in the following 34 days with the crystals continuously operating in oscillators. For the aging rates good correlation … WebThe recommended frequency stability or temperature tolerance of the crystal is ±50 ppm.
