APPLICATION INFORMATION
Crystal controlled oscillator circuits are widely used in
clock pulse generators because of their excellent
frequency stability and wide operating frequency range.
The use of the 74LVC1GX04 provides the additional
advantages of low power dissipation, stable operation over
a wide range of frequency and temperature and a very
small footprint. This application information describes
crystal characteristics, design and testing of crystal
oscillator circuits based on the 74LVC1GX04.
Crystal Characteristics
Figure 8 is the equivalent circuit of a quartz crystal.
The reactive and resistive component of the impedance of
the crystal alone and the crystal with a series and a parallel
capacitance is shown in Figure 9.

Fig.8 Equivalent circuit of a crystal.
Figure 9 also shows that with a specified load capacitance
(CL), the load resonance frequency (fL) is the same for a
circuit with either a series (b) or parallel (c) capacitance.
CL is specified by crystal manufacturers and is used in
determining the value of the external components of the
oscillator.
