Table 5 Crystal characteristics
CLOCK SYSTEMS
Crystal oscillator
The crystal is a conventional 2-pin design operating at
27 MHz. 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 shown in Fig.11. The crystal
characteristics are given in Table 5.
