NKG likes to introduce here technical information that we often share with our customers. When using a crystal in the field it is possible to face a frequency deviation when the crystal is used in the oscillator circuit. Our downloadable presentation here is explaining the reasons and how to workout the correct load for the crystal to be used.

When a crystal units is used in an oscillator circuit one shall make sure that the oscillator has enough reserves to startup the oscillation under all conditions. These parameters called Negative Resistance and Circuit Margin need to be tested and calculated, how to do this is introduced in our downloadable presentation.
