WebJan 15, 2024 · The Drive Level must not exceed the maximum value specified in the quartz data sheet. Fig. 2: In order to calculate the Drive Level, the current flowing through the quartz crystal is measured. Exceeding the maximum Drive Level may lead to frequency deviations or, in the worst case, even to failure of the quartz. 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,
WebApr 3, 2024 · As long as a crystal can accept drive levels up to 500μW, the USB chip is guaranteed not to overdrive the crystal. A 300μW maximum drive level crystal doesn't meet the specification, since it needs to at least handle a 500μW drive level per the table you've quoted. Share Cite Follow edited yesterday answered yesterday Kuba hasn't … WebCrystals below 30MHz are often specified at the fundamental frequency; above 30MHz they are typically specified as 3 rd, 5 th, or even 7 th overtone. (Overtones occur only at odd multiples.) Consequently, it is important to know whether the oscillator is operating in fundamental or overtone mode.
