Cseries = 4.5pf * 2 *(12.12059 – 12.09557)/12.12059 = 0.0186pf
The inductance L is given by:
L = 1 / ( 4 * pi*pi * Freq_series * Freq_series * Cs )
L = 1/(4*pi*pi*12.09557MHz^2*0.0185pf) = 9308 uH
The Q of the crystal is found by measuring the two frequencies F1 and F2 on either side
of the Freq_series where the phase angle is +/- 45 degrees.
Q = Freq_series / ( F2 - F1 )
Q = 12.09585/(12.09591 – 12.09578) = 93045
