Book Description
A thin film hybrid temperature compensated crystal oscillator has been developed which utilizes digital compensation techniques to maintain a stable output frequency with respect to changes in temperature. The digitally compensated crystal oscillator (DCXO) described has been designed to be compatible with automated manufacturing techniques in large volume production, a program with conventional compensated oscillator designs. A look-up table, where each temperature increment corresponds to a particular compensation value, is maintained in an electrically erasable read only memory (EEPROM).

Book Description
Crystal oscillators have been in use now for well over SO years-one of the first was built by W. G. Cady in 1921. Today, millions of them are made every year, covering a range of frequencies from a few Kilohertz to several hundred Mega hertz and a range of stabilities from a fraction of one percent to a few parts in ten to the thirteenth, with most of them, by far, still in the range of several tens of parts per million.Their major application has long been the stabilization of fre quencies in transmitters and receivers, and indeed, the utilization of the frequency spectrum would be in utter chaos, and the communication systems as we know them today unthinkable,'without crystal oscillators. With the need to accommodate ever increasing numbers of users in a limited spectrum space, this traditional application will continue to grow for the fore seeable future, and ever tighter tolerances will have to be met by an ever larger percentage of these devices.

Book Description
The purpose of this program is the further development of a high stability temperature compensated crystal oscillator (HSTCXO) initially developed under contract DAAB07-71-C-0136. This HSTCXO is digitally compensated and is intended for use as a reference frequency source in advanced tactical communications systems. The program is to include detailed investigations into critical areas of size reduction, compensation simplification, and performance improvement. Five advanced exploratory models of the digitally compensated HSTCXO are to be delivered.
