CLOCK SYSTEMS
Crystal oscillator
The crystal is a conventional Colpitts 3-pin design
operating at 27 MHz. The oscillator is sinusoidal and
linear, with a controlled output amplitude. This reduces the
radiated and conducted level of the 27 MHz fundamental
frequency, and reduces the power dissipation in the quartz
crystal. 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 as illustrated in Fig.13. The crystal
characteristics are given in Table 13.
