QUARTZ CRYSTAL OSCILLATOR CIRCUITS STUDY.

The purpose of this program 1s to compile a quartz crystal oscillator design handbook applicable in the frequency range of 1 KC to 200 MC. The objective of the handbook is to facilitate and systematize the design the quartz crystal oscillators to eliminate crystal misapplications, reduce design time and costs, and increase the reliability of operation. The handbook will not be directed at the design of ultra-stable crystal oscillators, but rather at the non-temperature controlled, medium stability crystal oscillator prevalent in many types of communications equipment. A design procedure is presented for two type of Pierce transistor oscillators in the 0.8 to 20 MC range. The first of these is a derivative of the basic Pierce circuit which, at the cost of a slight increase in circuit complexity, is capable of an increase output power relative to that of the basic circuit. This type of oscillator is considered useful for transmitterdriver applications. The second type is the basic Pierce circuit which will be useful in low power level applications such as the local oscillator in small signal mixing operations. Author
