Crystal drive level
Webare many causes of crystal aging, including excessive drive level, various thermal effects, and stress relief or buildup on the mechanical structures. Aging is typically specified in … Webexcessive drive to the crystal. Drive Level seen by the Crystal The drive level seen by the crystal can be approximated as: DL=ESR × IQ^2 Where; ESR = equivalent series resistance of the crystal IQ = current flowing the crystal in RMS It is important to note that driving a quartz crystal with a much higher drive may lead to quartz blank heating,
