Section 5 Clock Pulse Generators
5.1
Clock pulses can be supplied to the system clock divider either by connecting a crystal or ceramic
resonator, or by providing external clock input. Figure 5.2 shows a block diagram of the system
clock generator.
5.1.1
Figure 5.3 shows a typical method of connecting a crystal resonator. An AT-cut parallel-resonance
crystal resonator should be used. Figure 5.4 shows the equivalent circuit of a crystal resonator. A
resonator having the characteristics given in table 5.1 should be used.
