Section 18 Clock Pulse Generator
18.1
Clock pulses can be supplied either by connecting a crystal resonator, or by providing external
clock input.
18.1.1
Figure 18.2 shows a typical method of connecting a crystal resonator. An appropriate damping
resistance R
should be used.
Figure 18.3 shows the equivalent circuit of a crystal resonator. A resonator having the
characteristics given in table 18.2 should be used.
A crystal resonator with frequency identical to that of the system clock ( ) should be used.
