Abstract
32.768 kHz low frequency crystals are found in a large part of today’s embedded systems that use microcontrollers especially in battery supplied applications which need low power consumption1]. Their main role is to offer a stable time reference. There are situations in which time measurement is needed when the system works in a mechanically unstable environment (cars, industrial equipment). The paper presents the studies done on the behavior of 32.768 kHz quartz crystals that are part of embedded systems which operate in a vibrating environment, in terms of period and long-time jitter of the generated time reference signal. The investigations of this effect were done using a test bench especially designed for this purpose which can measure the presented parameters determined by controlled mechanical stimulus (waveform, amplitude and frequency of the vibrations).
