This article compares the warm-up performance of Oven-Controlled Crystal Oscillators (OCXOs) and Temperature-Compensated Crystal Oscillators (TCXOs). It explains that OCXOs have a significantly longer warm-up time, typically 2 to 15 minutes, due to the power-intensive process of heating an internal ... read more

While OCXOs (Oven-Controlled Crystal Oscillators) offer excellent frequency stability, they present several disadvantages in mobile devices. Their high power consumption reduces battery life, and their large size limits use in compact applications like wearables. Additionally, OCXOs are more expensi... read more
