TCXO vs. OCXO: Choosing the Right Crystal Oscillator for Frequency-Critical Applications

Frequency stability is one of the most misunderstood specifications in electronic component sourcing. Engineers often default to the oscillator type they used on a previous project, without revisiting whether it still fits the new design's temperature range, power budget, or accuracy requirement. Two of the most common choices for precision timing are the Temperature Compensated Crystal Oscillator (TCXO) and the Oven Controlled Crystal Oscillator (OCXO)....
