Contextual Info: AN934 APPLICATION NOTE TIMEKEEPER Calibration INTRODUCTION The term “quartz accurate” has become a familiar phrase used to describe the accuracy of many time keeping functions. Quartz oscillators provide an accuracy far superior to other conventional oscillator designs, but they are not perfect. Quartz crystals are sensitive to temperature variations. Figure 1 shows the
