A crystal oven is a temperature-controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature, in order to prevent changes in the frequency due to variations in ambient temperature.

2023年5月5日 · OCXO称为恒温晶体振荡器（Oven Controlled Crystal Oscillator），是利用恒温槽使晶振中石英晶体谐振器中的温度保持恒定，将由周围温度变化引起的振荡器输出频率变化量削减到最小的晶体振荡器。

恒温晶振（Oven Controlled Crystal Oscillator，OCXO）是一种高精度频率基准，本质上是一个小型电子系统。 OCXO与驯服晶振（GPSDO）、铷原子钟一样重要，而且性价比更高，用途也更加广泛。

In this blog, we'll review the basics of how an OCXO works, the terms you need to know, how to determine the turning point, and the differences between AT and SC crystal cuts. An OCXO is a temperature-controlled device that maintains a quartz crystal's constant operating temperature.

The OCXO, which stands for Oven Controlled Crystal Oscillator, provides optimal frequency stability by heating an SC-cut crystal and critical circuitry to a single temperature and maintaining that temperature over a range of environmental temperature changes.

OCXO actually stands for Oven Controlled Crystal (Xtal) Oscillator. OCXO are the top performing type of quartz crystal oscillator at the expense of power. Other types of quartz crystal oscillators include TCXO, VCXO, and just plain XOs. You can read more about all the different types of quartz crystal oscillators here.

Oven-Controlled-Crystal-Oscillator (OCXO) is a reference oscillator having excellent temperature stability and low phase noise. These are the key parameters of an OCXO. OCXOs utilizes a small, highly accurate oven to improve frequency stability versus ambient temperature.

2024年4月30日 · Oven controlled crystal oscillators (OCXOs) are a highly précised clock type of crystal oscillator widely used in extremely accurate and stable frequency signals. The enclosure or oven is responsible for controlling and regulating the temperature of the crystal to a …

恒温晶体振荡器简称恒温晶振，英文简称为OCXO（Oven Controlled Crystal Oscillator）,是利用恒温槽使晶体振荡器中石英晶体谐振器的温度保持恒定，将由周围温度变化引起的振荡器输出频率变化量削减到最小的晶体振荡器。

It consists of an oven-controlled circuit, a temperature sensor, and the crystal oscillator itself. The improved stability stems from the OCXO’s ability to maintain a constant crystal temperature, irrespective of ambient temperature changes.
