Oscillator startup and Negative R
One of the main failure modes for any clock is startup! Crystal specifications must be taken into consideration during oscillator circuit design. Lower cost crystals put more strain on oscillator circuit designers to provide robust startup conditions while not sacrificing reliability or other potential failure modes. Dominant Failure Mode for an Oscillator Circuit with Low Negative R or High Crystal Resistance is the oscillator failing to start when power is applied to the circuit.
