1至60 MHz,±50-PPB精密超级TCXO

SIT5348是一个坚固化±50-PPB Endura™超精密超级TCXO,加速灵敏度低至0.004 ppb /g。该设备专为恶劣环境而设计,是高可靠性航空航天和防御应用的理想选择。通过利用寿星独特的Dualmems™温度传感和TurboComppenation™技术,SIT5348在环境压力源存在下提供最稳定的时机 - 气流,温度扰动,振动,冲击和电磁干扰(EMI)。

This MEMS-based Endura Super-TCXO can be factory-programmed to any combination of frequency, stability, voltage, and pull range. This programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency is custom built.

SIT5348符合MIL-PRF-55310和MIL-STD-883规格。
