4.2
Clock pulse can be supplied to the system clock divider either by connecting a crystal or ceramic
oscillator, or by providing external clock input.
Connecting a Crystal Oscillator: Figure 4.2 shows a typical method of connecting a crystal
oscillator.
Figure 4.3 shows the equivalent circuit of a crystal oscillator. An oscillator having the
characteristics given in table 4.1 should be used.
