WebCrystal Oscillator Aging Page 1 of 3 146-000A This technical note is to help customers specify aging of crystal oscillators. Long term frequency drift is an important characteristic of crystal oscillators and is specified by an aging requirement. If the nature of aging is not understood, aging requirements may be improperly specified. WebTo achieve a sufficient long term stability the complete oscillators need preaging and a stable process of the crystal production. While low-cost oscillators just give an overall stability all stability parameters are clearly defined for most of the professional oscillators. mount blue onlineWeb1) Long term instabilities – These are slow changes in oscillator frequency over time (e.g., minutes, hours, or days), generally due to temperature changes and/or oscillator aging. For good oscillators, this instability is measured in parts per million (ppm). Parts per million is a similar to describing the instability in mountblow road clydebank g81 4sl
