APPLICATION NOTE 2127
Modeling of Quartz Crystal

This application note, describes a method for modeling a crystal, with loading capacitance.

Clock generator (CLK gen) designers can use a crystal model to easily determine the loading capacitance for a
required frequency. Circuit and system designer can use the model to simulate the behavior of crystal
oscillators.

To model a crystal, we use a simple circuit to measure the oscillation frequencies under different loading
capacitance. Then,
