About this course

In this class, we explore common challenges and compromises when designing quartz oscillators. We’ll look at the frequency budget for the life of the product, short- and long-term aging, frequency tolerances, load and voltage stability and how each is tested. Finally, we’ll discuss performance differences based on how the product is installed.
