System Clock Generator

Clock pulses can be supplied to the system clock divider either by connecting a crystal or ceramic

oscillator, or by providing external clock input.

(1) Connecting a Crystal Oscillator

Figure 4.2 shows a typical method of connecting a crystal oscillator. For information on

recommended resonators, see the product AC characteristics listed in section 16, Electrical

Characteristics. Please consult with the resonator manufacturer when selecting a resonator model.

(2) Connecting a Ceramic Oscillator

Figure 4.3 shows a typical method of connecting a ceramic oscillator. For information on

recommended resonators, see the product AC characteristics listed in section 16, Electrical

Characteristics. Please consult with the resonator manufacturer when selecting a resonator model.
