Crystal Oscillator
The equivalent schematic of the crystal with its parameters specified by the crystal manufacturer
can be taken from the subsequent figure.
Here also the load capacitance of the crystal CL, which the crystal wants to see in order to oscillate
at the desired frequency, can be seen.
