1 to 60 MHz, ±50-ppb precision Super-TCXO

The SiT5348 is a ruggedized ±50-ppb Endura™ ultra-precision Super-TCXO with an acceleration sensitivity as low as 0.004 ppb/克克ydF4y2Ba. This device is engineered for harsh environments and is ideal for high-reliability aerospace and defense applications. By leveraging SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology, the SiT5348 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

这种基于MEMS的Endura Super TCXO可以在工厂编程为频率、稳定性、电压和拉力范围的任意组合。这种可编程性使设计人员能够优化时钟配置,同时消除与石英TCXOs相关的长前置时间和定制成本,其中每个频率都是定制的。克ydF4y2Ba

The SiT5348 conforms to MIL-PRF-55310 and MIL-STD-883 specifications.
