clocked from a single crystal. Since Microchip does not

recommend connecting other logic to the PICmicro’s internal oscillator circuit, an external crystal oscillator circuit is recommended. Each device will then have an external clock source, and the number of devices that can be driven will depend on the buffer drive capability. This circuit is also useful when more than one device (PICmicro) needs to operate synchronously to each other.
Either a prepackaged oscillator can be used or a simple oscillator circuit with TTL gates can be built. Prepackaged oscillators provide a wide operating range and better stability. A well-designed crystal oscillator will provide good performance with TTL gates. Two types of crystal oscillator circuits can be used; one with series resonance, or one with parallel resonance.
This circuit is also designed to use the fundamental frequency of the crystal.
