The crystal oscillator is a conventional 2 pin design operating at 15 to
50.4
MHz. This oscillator is also capable of
operating with a ceramic resonator. It is capable of oscillating with both fundamental and third overtone mode crystals.
External components should be used to suppress the fundamental output of the third overtone types as illustrated in
Fig.25.
