Choosing the right quartz crystal cut—AT-cut versus SC-cut—directly determines OCXO frequency stability and precision timing performance. The crystal’s cutting angle defines its temperature-frequency curve, affecting drift, turnover point, and stress sensitivity. While AT-cut crystals offer moderate... read more

This article explains how the angle and thickness of quartz crystals are determined in manufacturing, directly impacting frequency stability and performance. It details common crystal cuts (AT, SC, BT) and their applications, along with the mathematical relationship between thickness and resonant fr... read more
