1到60 MHz, ±0.1 to ±2.5 ppm AEC-Q100 Super-TCXO

The SiT5386 is an AEC-Q100 automotive-grade ±100 ppb precision MEMS Super-TCXO. This device is based on the Elite Platform and is engineered for best dynamic performance. By leveraging SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, the SiT5386 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

坐5386 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.
