Section 22 Clock Pulse Generator
22.2
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock.
22.2.1
A crystal oscillator can be connected as shown in the example in figure 22.2. Select the damping
resistance R
When a clock is supplied with a crystal resonator connected, the frequency of the crystal resonator
should be 8 MHz to 25 MHz.
Figure 22.3 shows the equivalent circuit of the crystal oscillator. Use a crystal oscillator that has
the characteristics shown in table 22.2.
