为什么TCXO有削波的正弦波输出？

大多数陶瓷LCC封装的ref="http://www.guanjiedz.com/OSCillatorCrystal.html" title="TCXO晶振" target="_blank">TCXO晶振仅提供削波正弦波输出。这样做的原因有很多，尽管它让许多想要CMOS输出电平的电路设计人员感到沮丧。

ref="/RakonCrystal.html" title="瑞康晶振" target="_blank" style="word-spacing: -1.5px;">Rakon晶振针对太空市场的频率控制解决方案可应对最极端的环境挑战——极端温度、太空辐射、振动和巨大的 G 力。尽管如此，他们必须完美地运作，因为失败不是一种选择。Rakon是航天和高可靠性市场的世界领导者，是欧洲最大的航天级振荡器和谐振器独立生产商。

Rakon 在提供高可靠性产品方面有着悠久的历史，一些客户与 Rakon 有 30 年或更长时间的合作关系。许多政府机构和商业项目在全球范围内使用 Rakonref="/Products/CTSVFAC170.html" title="有源晶体振荡器" target="_blank" style="word-spacing: -1.5px;">有源晶体振荡器，用于在最苛刻条件下需要高性能的系统中。Rakon宣布推出两款新的太空级晶体谐振器，进一步扩展了其高可靠性太空解决方案的范围。RHX3500 和 RHX3700 的设计、完全制造和测试均遵循 MIL-PRF-3098 指南。

Rakon一直是欧空局认证的合格空间晶体谐振器供应商。它的高可靠性ref="http://www.guanjiedz.com/khhf.html" title="晶体谐振器" target="_blank">晶体谐振器是可用的，并在恶劣的机械环境中提供高稳定性。它们被密封在真空或中性气体中 (氮气)根据应用在冷焊或电阻焊中。 Rakon的太空合格晶体是根据欧洲航天局的合格PID(过程识别)制造的。此外，基于其ref="http://www.guanjiedz.com/SMDcrystal.html" title="石英晶体" target="_blank">石英晶体能力，Rakon还提供了超过20年的最先进的超稳定，通过使用拉肯公司的QAS(自悬浮石英)晶体谐振器来保证出色频率稳定性的振荡器 在里面。

基于这种长期的空间遗产和经验的空间合格的晶体谐振器非常高性能的振荡器，Rakon现在提供完全按照MIL-PRF-3098指南制造和测试的晶体谐振器。
