Remark ( see figure 3 )
Fo : Load resonance frequency
fr : Resonance frequency
Fo = fr ×{ C1/ ( 2×( Co + CL ))+ 1 } ( Hz )
R1 : Motional resistance
C1 : Motional capacitance
Co : Shunt capacitance
CL : Load Capacitance
Figure 3 Equivalent circuit of crystal unit, and CL
Remark ( see figure 4)
Approximate formula of the load capacitance
of the circuit CL.
CL = Cg×Cd / (Cg + Cd) + Cs (pF)
Where Cs(=2 to 4pF) Stands for stray capacitance of the circuit.
Cos : X1_X2 Stray capacitance
Cgs : X1_Vss Stray capacitance
Cds : X2_Vss Stray capacitance
Figure 4 Stray capacitance Cos,Cgs,Cds of the circuit
Resonator circuit constants will differ depending on the resonator element, stray capacitance in its
interconnecting circuit, and other factors. Suitable constants should be determined in consultation
with the resonator element manufacturer.
