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 the example in figure 21.2. Select the damping resistance
R
When providing the clock from the crystal resonator, the frequency should be in the range of 8 to
18 MHz.
Table 21.2 Damping Resistance Value
Figure 21.3 shows an equivalent circuit of the crystal resonator. Use a crystal resonator that has
the characteristics shown in table 21.3.
