They are designed and manufactured to meet a high degree of reliability (lifetime more than 15 years) under normal …commercial“ application conditions. Products dedicated for automotive and H-Rel applications are specifically identified for these applications. If you intend to use these …commercial“ products for airborne, space or critical transport applications, nuclear power control, medical devices with a direct impact on human life, or other applications which require an exceptionally high degree of reliability or safety, please contact the manufacturer.Electrostatic SensitivityCrystal oscillators are electrostatic sensitive devices. Proper handling according to the established ESD handling rules as in IEC 61340-5-1 and EN 100015-1 is mandatory to avoid degradations of the oscillator performance due to damages of the internal circuitry by electrostatics. If not otherwise stated, our oscillators meet the requirements of the Human Body Model (HBM) according to JESD22-A114F.HandlingExcessive mechanical shocks during handling as well as manual and automatic assembly have to be avoided. If the oscillator was unintentionally dropped or otherwise subject to strong shocks, please verify that the electrical function is still within specification.Improper handling may also detoriate the coplanarity of bended leads of SMD components. SolderingOscillators can be processed using conventional soldering processes such as wave soldering, convection, infrared, and vapour phase reflow soldering under normal conditions. Solderability is guaranteed for one year storage under normal climatic conditions (+5°C to +35°C @ 40% to 75% relative humidity), however typically sufficient solderability –depending on the process – is maintained also for longer time periods. In cases of doubt, components older than one year should undergo a sample solderability test.The recommended reflow solder profile for SMT componets is according IPC/JEDEC J-STD-020 (latest revision)SMD oscillators must be on the top side of the PCB during the reflow process.After reflow soldering the frequency of the products may have shifted several ppm, which relaxes after several hours or days, depending on the products. For details please contact the manufacturer.CleaningCleaning is only allowed for hermetically sealed oscillators. Devices with non hermetical enclosures (e.g. with trimmer holes) shall not be cleaned by soaking or in vapour, because residues from the cleaning process may penetrate into the interior, and degrade the performance.Our products are laser marked. The marking of our oscillators is resistant to usual solvents, such as given in IEC 60068-2-45 Test XA. For applicable test conditions see IEC 60679-1.Ultrasonic cleaning is usually not harmful to oscillators at ultrasonic frequencies of 20kHz at the sound intensities conventional in industry. Sensitive devices may suffer mechanical damage if subjected to 40kHz ultrasound at high sound pressure. In cases of doubt, please conduct tests under practical conditions with the oscillators mounted on the PC board.Hermetical SealIf the device is specified as hermetically sealed, it meets the requirements of IEC 60679-1, i.e. for enclosures with a volume smaller than 4000mm³ the leak rate is below 5*10-8 bar cm3/s, for larger enclosures it is below 1*10-6 bar c bar cm3/s, tested according to IEC 60068-2-17 Test Qk.Glass feed-throughs may be damaged as a result of mechanical overload, such as bending the connection leads or cutting them with an unappropriated tool. In order to avoid microcracking, the wire must be held fixed in position by a pressure pad between glass feed-through and the bending point during the bending process. Check: there should be no damaged edges on the glass feed-through after the bending.Tape & ReelThe packing in tape and reel is according to IEC 60286-3.Details see tape & reel data sheets.QualificationVectron products are undergoing regular qualification/reliability tests as per product family definition. Results are available upon request. Customer specific qualification tests are subject to agreement.If not otherwise stated, the product qualifications are performed according to IEC 60679-5 or other valid industry standards.ScreeningOur oscillators are 100% tested, and all key manufacturing processes are controlled by Statistical Process Control (SPC). Additional screening is therefore usually not required.On request, we can perform screening tests according to MIL-PRF-55310, class B for discrete or hybrid constructions of commercial (COTS) products. For special requirements see the High Reliability Clock section.Demounting/Desoldering of Ocsillator device for analysis:The removal or desoldering of oscillators from customer application after SMT process may cause damage to the device if not handeld appropriately. It may lead to parametric change such as frequency shift (like OCXO: up to +/- 200 ppb) . It is utmost important to minimize the direct heat exposure to the device in order to avoid such effects. Use of hot air gun for desoldering should be avoided.A mechanical stress could also destroy the part, if exposed to excessive mechanical shock after removal process. Appropriate shock protection & ESD designated packaging must be used to avoid any external mechanical shock for FA return process.In general, the products* withstand the tests listed in the following Table 1, which are based on valid industry standards.*Additional note: Test conditions could vary for different product families and individual product specifications depending on the customer as well as product requirements.Recommended Environmental Test ConditionsTable 1。
晶振选型的参数
晶振选型的参数1.、频率大小：频率越高一般价格越高。
但频率越高，频差越大，从综合角度考虑，一般工程师会选用频率低但稳定的晶振，自己做倍频电路。
总之频率的选择是根据需要选择，并不是频率越大就越好。
要看具体需求。
比如基站中一般用10MHz的恒温晶振（OCXO），因其有很好的频率稳定性，属于高端晶振。
至于范围，晶振的频率做的太高的话，就会失去意义，因为有其他更好的频率产品代替。
JFVNY的产品频率范围是：25kHz-1.3G，基本上所有应用中的晶振都可以在JFVNY产品种找到。
2.、频率稳定度：关键参数，JFVNY的高端晶振可以达到10-9级别。
指在规定的工作温度范围内，与标称频率允许的偏差，用PPm （百万分之一）表示。
一般来说，稳定度越高或温度范围越宽，价格越高。
对于频率稳定度要求±20ppm或以上的应用，可使用普通无补偿的晶体振荡器。
对于介于±1 至±20ppm 的稳定度，应该考虑温补晶振TCXO 。
对于低于±1ppm 的稳定度，应该考虑恒温晶振OCXO。
如果客户有十分特别的频稳要求，JFVNY可根据客户要求参数定做。
2、电源电压：常用的有1.8V、2.5V、3.3V、5V等，其中3.3V应用最广。
3、输出：根据需要采用不同输出。
（HCMOS，SINE，TTL，PECL，LVPECL，LVDS，LVHCMOS等）每种输出类型都有它的独特波形特性和用途。
应该关注三态或互补输出的要求。
对称性、上升和下降时间以及逻辑电平对某些应用来说也要作出规定，根据客户需要我们可以帮助客户选型。
5.、工作温度范围：工业级标准规定的-40～+85℃这个范围往往只是出于设计者们的习惯，倘若-20℃～+70℃已经够用，那么就不必去追求更宽的温度范围。
对于某些特殊场合如航天军用等，对温度有更苛刻的要求。
6.、相位噪声和抖动：相位噪声和抖动是对同一种现象的两种不同的定量方式，是对短期稳定度的真实度量。
晶振选型与应用知识
石英晶振选型与应用知识石英晶体是压电晶体的一种，沿着特定的方向挤压或拉伸，它的两端会产生正负电荷，这种效应称为正压电效应；相反，对晶体施加电场导致晶体形变的效应，称为逆压电效应。
所以在石英晶片两面施加交变电场，晶片就会产生形变，而形变又会产生电场，这是一个周期转换的过程。
对于特定的晶片，这个周期是固定的，我们利用这个周期来产生稳定的基准时钟信号。
石英晶体元器件，是利用石英晶体的压电效应实现频率控制、稳定或选择的关键电子元器件。
包括石英晶体谐振器、石英晶体振荡器和石英晶体滤波器。
在石英晶片的两面镀上电极，经过装架、调频、封装等工序后制成石英晶体元件。
石英晶体元件与集成电路等其它电子元件组合成石英晶体器件。
本文主要介绍石英晶振：即所谓石英晶体谐振器（无源晶振）和石英晶体振荡器（有源晶振）的统称。
一般的概念中把晶振就等同于谐振器理解了，振荡器就是通常所指钟振。
石英晶振是一种用于稳定频率和选择频率的电子元件，已被广泛地使用在无线电话、载波通讯、广播电视、卫星通讯、仪器仪表等各种电子设备中.一、石英晶振的型号命名方法1.国产石英晶体谐振器的型号由三部分组成：–第一部分：表示外壳形状和材料，B表示玻璃壳，J表示金属壳，S表示塑料封型；–第二部分：表示晶片切型，与切型符号的第一个字母相同，A表示AT切型、B表示BT切型，–第三部分：表示主要性能及外形尺寸等，一般用数字表示，也有最后再加英文字母的。
JA5为金属壳AT切型晶振元件，BA3为玻壳AT切型晶振元件。
2石英晶体振荡器的型号命名有四部分组成：.–第一部分：主称用大写字母Z表示石英晶体振荡器；–第二部：类别用大写字母表示，其意义见下表：–第三部分：频率稳定度等级用大写字母表示，其意义见下表：–第四部分：序号用数字表示，以示产品结构性能参数的区别从型号上无法知道晶振元件的主要电特性，需查产品手册或相关资料才行。
二、石英晶振的结构特点1.石英晶体谐振器一般由外壳、晶片、支架（金属座）、外引线、引线等组成。
