Quartz is the material of choice for stable resonators, as it is one of the few piezoelectric crystals that has very high Q and is also highly anisotropic.  Read more »

Typically when we talk about crystals, we are referring to crystals using the fundamental vibration mode of AT-cut quartz.  Read more »

The image below is a common diagram implementing a crystal.  An even more common question is what is the purpose or function of the capacitors tied onto either terminal of the crystal? Read more »

We often discuss the complex designs that oscillators can achieve, but rarely stop and think about a fundamental component: the quartz crystal.  Read more »
