60 to 220 MHz, ±0.5 to ±2.5 ppm Super-TCXO

The SiT5147 is a ruggedized ±0.5 to ±2.5 ppm Endura™ Super-TCXO with an acceleration sensitivity as low as 0.004 ppb/g高达105°C的温度高。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。通过利用寿势的独特Dualmems™温度传感和TurboComppenation™技术,SIT5147在环境压力源存在下提供稳定的时机 - 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.
