Lowering the drive level can reduce the aging effects. The aging effect an overdriven crystal experiences in one month can be as much as that of a 1-year-old crystal that is driven at the rated power level. Figure 6 shows a typical aging plot. Figure 6.

WebOne of the most common crystal designs is the AT Cut crystal and will be the referenced crystal type through-out this application note. For frequencies above 1MHz, only the … WebDec 10, 2008 · Most oscillator circuits use nonlinear limiting rather than a control loop to define the amplitude, thus the output is can't be clean sine wave. If you refer to usual crystal oscillator devices, they have square wave output except for some special high frequency oscillators.

WebIt is almost always better to connect such inputs to the correct logic level than to leave them floating. From your description, the input "floats up" and appears to operate correctly. If that were guaranteed by the manufacturer (because the chip has a built in pull up, for example) then leaving it unconnected would be fine. – JRE WebWe would like to show you a description here but the site won’t allow us. chair cushions custom made
