60至220 MHz,±50 ppb超级TCXO

The SiT5359 is a ±50 ppb high-frequency MEMS Precision Super-TCXO. This device is engineered for best dynamic performance. It is fully compliant to the GR-1244 Stratum 3 oscillator specifications. By leveraging SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, the SiT5357 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

SIT5359可以进行工厂 - 编程到频率,电压和拉伸范围的任何组合。该可编程性使设计人员能够优化时钟配置,同时消除与Quartz TCXO相关联的长时间的时间和定制成本,其中每个频率是自定义的。
