Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of crystals?
3 answers
Answers:
Worst case - oscillation can stop and if this is major clock frequency for PC what ever a complete system can fail. Can not remember which time, but for satellite this happened in the past and this of course is a disaster. Also if base stations may fail due to such a problem, many people are affected.
~Joerg K., Technical Manager, Essen, Germany
Wrong load capacitance resulted in too small pulling for set frequency.
~Geoff L, Design Engineer, Mechanicsburg, PA
Too little oscillator allowance.
~Juerg K, Manufacturer, Grenchen, Switzerland
