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

The SiT5157 Super-TCXO is a highly flexible, tight-stability oscillator capable of supporting up to 220 MHz. Based on SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, this device delivers excellent dynamic performance in the presence of common environmental hazards, such as airflow, temperature perturbation, vibration, shock, power supply noise and electromagnetic interference (EMI). The SiT5157 is engineered for high-reliability systems in industrial, server and storage, networking and telecom.

SIT5157可以进行工厂编程到频率,稳定性,电压和拉伸范围的任何组合。该可编程性使设计人员能够为MEMS TCXO配置进行定制以获得最佳系统性能,同时消除与石英设备相关的长的提前时间和定制成本。
