Crystal Oscillator Aging

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. The modeling presented here has been used by ISOTEMP RESEARCH, INC. for many years and concurs with MIL-0-55310B.
