Section 21 Clock Pulse Generator
21.2
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock.
21.2.1
A crystal resonator can be connected as shown in the example in figure 21.2. Select the damping
resistance R
Figure 21.3 shows the equivalent circuit of the crystal resonator. Use a crystal resonator that has
the characteristics shown in table 21.2. When a crystal resonator is used, the range of its
frequencies is from 8 to 25 MHz.
