COURSE # TOO-380
HIGH STABILITY RESONATOR CRYSTAL TECHNOLOGY
A complicated topic presented in down to earth terminology, accompanied by numerous examples and invaluable manufacturing hints.
Unabated worldwide proliferation of communication devices, ranging from garage door openers to cellular telephones, necessitates efficient use of frequency spectrum. Crystal oscillators are the most widely used technology that meet the challenges of frequency stability, noise, size and cost. The design criteria for a crystal resonator, the heart of a crystal oscillator, is the topic of this course that unveils, in simple language, the physical principles, design criteria and optimization
leading to a final product.
Who will benefit:
Design criteria of a high stability crystal are of utmost importance to both the crystal designer and the crystal user. This course will benefit the technical and technical marketing staff of crystal growers and crystal resonators manufacturers, as well as the technical staff of communication
equipment manufacturers and FCC regulators.
You will benefit by enhancing your knowledge of the:
- T-1, T-3, SONET, Frame Relay, ATM,
- physics of piezoelectricity
- concepts of crystallography
- temperature stabilization
- design optimization criteria
- modern manufacturing processes
