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
74AUP1Z04 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 74AUP1Z04.
