Seismic Sensors

Seismic sensors are often placed in remote locations, where they are subjected to harsh conditions, and in areas where the connection to the satellite reference may be unreliable. Yet the sensor must continue to provide accurately time-stamped data. SiTime MEMS timing solutions provide the essential reliability and accuracy needed for seismic sensors.

With OCXO-level stability over temperature, SiTime precision Super-TCXOs are optimized for accurate time stamping for extended periods of operation. For power-sensitive applications, SiTime µPower TCXOs provide an accurate low-power reference. These MEMS TCXOs deliver extreme environmental robustness under harsh conditions.
