恒温晶体振荡器OCXO( Oven Controlled Crystal Oscillator),是目前频率稳定度和精确度最高的晶体振荡器。它在老化率、温度稳定性、长期稳定度和短期稳定度等方面的性能都非常好,作为精密的时频信号源被广泛用于全球定位系统通信、计量、频谱及网络分析仪等电子仪器中。目前,绝大多数高稳定度晶体振荡器都采用了将晶体恒温的方法,使用精密的恒温控制槽,将槽内温度调节到晶体谐振器的零温度系数点上。这样,能最大限度地克服温度对晶体振荡器频率的影响,被广泛用作标准频率源。恒温晶体振荡器包括以下几个基本组成部分。

The constant temperature crystal oscillator OCXO (Oven Controlled Crystal Oscillator) is the crystal oscillator with the highest frequency stability and accuracy. It has good performance in aging, temperature stability, long-term stability and short-term stability. As a precise time frequency signal source, it is widely used in electronic instruments such as global positioning system communication, measurement, spectrum and network analyzer. At present, most high stability crystal oscillators adopt the method of crystal constant temperature, and use the precise constant temperature control slot to adjust the temperature in the slot to the zero temperature coefficient point of the crystal resonator. In this way, the effect of temperature on the crystal oscillator frequency can be maximally overcome, and is widely used as a standard frequency source. The constant temperature crystal oscillator includes the following basic components.

1.High precision quartz crystal resonator

1.高精度的石英晶体谐振器

Quartz crystal resonator is the core component of oscillator circuit. The correct choice of tangential angle is a necessary condition for making quartz resonators with good frequency and temperature coefficient, especially the quartz resonator used in a wide temperature range. At present, there are two kinds of quartz resonators used in constant temperature crystal oscillator, AT and SC. They have the characteristics of small frequency temperature coefficient, high Q value and low aging effect.

石英晶体谐振器是振荡电路的核心元件。正确选择切角是制作频率温度系数好的石英谐振器的必要条件,特别是在宽温度范围内使用的石英谐振器更是如此。目前恒温晶体振荡器中常用的石英谐振器有AT切和SC切两种。它们具有频率温度系数小,Q值高,老化效应小等特点。

2. stable oscillating circuit

2.稳定的振荡电路

As the constant temperature crystal oscillator requires high frequency stability, the stability of the oscillating circuit itself is also decisive in addition to a certain temperature control precision in the temperature control circuit. The basic function of the oscillating circuit in a thermostatic crystal oscillator is to convert the DC energy into an alternating current with a certain frequency, amplitude and high stability. This conversion is carried out with the participation of quartz resonators. The most prominent problem is the stability of frequency. Therefore, the analysis and design of oscillatory circuits take this as the premise.

由于恒温晶体振荡器要求频率稳定度高,除了在控温电路方面要达到一定的控温精度外,振荡电路本身稳定性也是起决定性作用的。恒温晶体振荡器中振荡电路的基本功能就是把直流电能转变成具有一定频率、幅度且频率高度稳定的交流电能,这种转换是在石英晶体谐振器的参与下进行的。其中最突出的问题就是频率的稳定性。所以分析、设计振荡电路都以此为前提。

3. precision thermostat box with perfect structure and good temperature control

3.结构完善、温控良好的精密恒温箱

The precision thermostat is a constant temperature system composed of thermostat, temperature control circuit and other auxiliary devices. In a crystal oscillator, the quartz resonator and the relevant circuit elements are kept at constant temperature. The function of the quartz resonator is to stabilize the temperature of the quartz resonator at the turning point temperature of the quartz resonator, so as to give full play to the small frequency temperature coefficient of the quartz resonator near the turning point temperature, so that it can be used reasonably. The design of a constant temperature slot which meets the requirements and the selection of a good temperature control circuit plays an important role in stabilizing the frequency. Therefore, a high stable crystal oscillator, not only should have stable oscillating circuit, but also must have a good performance thermostat to ensure the stability of the frequency, both are indispensable. With the gradual improvement of the stability requirements of the crystal oscillator, the demand for temperature control precision of the thermostat is getting higher and higher. At present, the temperature control accuracy of the constant temperature box should be within 0.001 centigrade at the frequency stability of the crystal oscillator at the order of 100~10.
With the continuous improvement of communication technology, the demand for constant temperature crystal vibration is becoming more and more high, making it constantly towards high precision and high stability, low noise and high frequency, low power, fast start, miniaturization.

精密恒温箱是由恒温槽,温度控制电路及其它辅助装置组成的恒温系统。在晶体振荡器中,用来使石英谐振器和有关电路元件保持恒温。其作用是把石英晶体谐振器的温度稳定在石英谐振器的拐点温度处,从而充分发挥拐点温度附近石英谐振器的频率温度系数小的特性,使其得到合理使用。设计一个符合要求的恒温槽和选择一个性能良好的温度控制电路对稳定频率起着举足轻重的作用。因此一个高稳定的晶体振荡器,不但应具有稳定的振荡电路,而且还必须有性能良好的恒温箱来保证其频率的稳定,两者缺一不可。随着对晶体振荡器稳定度要求的逐步提高,对恒温箱的控温精度要求也越来越高,目前,频率稳定度在100~10量级的晶体振荡器,其恒温箱的温度控制精度应在0.001℃以内。

随着通信技术的不断提高,对恒温晶振的要求越来越高,使其不断向着高精度与高稳定化,低噪声与高频化、低功耗、快启动、小型化方向发展。

很多客户都会经常在问温补晶振也是属于有源晶振的一种,那为什么会和石英晶体振荡器会有着天大的区别呢,一个在天上,一个在地下.温补晶振与普通的石英晶体振荡器的不同就是温补晶振的精度会比石英晶体振荡器的性能要更高,稳定性会更强.对于晶振频率来说,温补晶振可以起到一个温度补偿的作用.温补晶振也称TCXO晶振,传统的TCXO晶振提通过采用模拟器件进行温度补偿,通过改变振荡回路中的 负载电容等模拟器件让其随着温度变化来补偿晶体谐振器由于环境温度变化所生产的频率漂移.

由于石英晶体振荡器具有良好的稳定性,在通信、测量、时钟、控制等领域得到了广泛的应用,对高精度的频率输出.随着频率稳定性的要求越来越严格,在许多场合中,选择购买振荡器的频率比晶体单元要好,可以很容易地获得具有高稳定性的频率输出,而只提供给振荡器.这里我们要提到的是,石英晶体振荡器是指晶体单元的联合单位和反馈电路的放大器.

石英晶振是有源晶振和无源晶振的统称，然而石英晶振包含着插件石英晶振和石英贴片晶振，现具体的来说说无源图片石英晶振，也就是被人们通常称为石英晶体谐振器，其中的那个封装形式有其下几类：SMD2016、SMD2520、SMD3225、SMD3215、SMD5032、SMD7015、SMD7050、SMD2012。以上这些晶振封装中包含了金属面封装和陶瓷面封装

我们都知道有源晶振价格上要高于无源晶振很多，但你有没有发现现在越来越多的电子产品都选择使用成本更高的石英晶体振荡器呢？对于这个现象，作为晶振销售员的小编是有深深的体会，那到底是什么原因让本应该遵守最低成本生产守则的电子产品们纷纷向有源振荡器伸去橄榄枝呢？下面和小编一起来分析分析有源晶振到底有什么不同之处吧！

振荡器可以说是晶振各分类中内容知识最丰富的一种类型，和基本电气性能一致谐振器与滤波器分类不同，各种不同振荡器分类电气性能适应环境有着千差万别的区分，目前常见的振荡器有OSC振荡器、TCXO振荡器、VCXO振荡器、VC-TCXO振荡器、差分振荡器、OCXO振荡器、32.768K振荡器、时钟振荡器和可编程振荡器。其中32.768K振荡器和可编程振荡器可以说是新生不久，是目前各大振荡器生产厂家最为关注的晶振发展方向。
