the oscillation allowance (negative resistance) in the final target system (layout) to
determine the optimum parameters for oscillator operation.
The manufacturers of crystals and ceramic resonators offer an oscillator
evaluation service. This evaluation checks the crystal/resonator specification
limits to ensure a reliable oscillator operation.
