Types of Crystal Oscillators TCXO, OCXO, VCXO Explained by ‪@Electronishq‬ Chapters: 00:00 Introduction 00:13 Standard Crystal Oscillator (XO) & Instability 01:24 TCXO (Temperature Compensated) 03:05 OCXO (Oven Controlled) 05:01 VCXO (Voltage Controlled) & Tuning 06:24 Comparison Matrix: Choosing the Right Oscillator 07:34 Summary: The Hierarchy of Stability 08:02 Exam Notes Folks there is a small technical correction regarding the OCXO curve at 3:26. The Frequency vs. Temperature graph for OCXO crystals (typically AT-cut or SC-cut) is actually Cubic (S-shaped), not Quadratic (U-shaped). The parabolic curve shown in the slide is just a zoomed-in approximation of the crystal's 'turnover point' (the upper inflection peak) where the oven operates. Standard AT-cut crystals are third-order polynomials, not parabolas. Thanks!
