60至220 MHz,±0.1至±2.5 ppm AEC-Q100超级TCXO

The SiT5387 is an AEC-Q100 automotive-grade ±100 ppb high-frequency MEMS Precision Super-TCXO. This device, based on the Elite Platform, is engineered for best dynamic performance. By leveraging SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, the SiT5387 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

SIT5387可以进行工厂用于频率,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。
