SiTime, Silicon MEMS Oscillators and Clock Generators

High-Temp Oscillators for Industrial and High Reliability Applications

E-mail Print

SiTime's high-temp oscillators deliver ±20 PPM frequency stability from -55 °C to 125 °C. They are 2x better in stability, 20x more reliable and 30x more resistant to shock and vibration compared to quartz. SiTime oscillators enable higher system performance and reduce field failures in harsh environments.

Key Features:

  • 1 to 137 MHz with 6 decimal places of accuracy
  • Military (-55 to 125 °C), Automotive (-40 to 125 °C), Ext. Industrial (-40 to 105 °C)
  • Low vibration sensitivity (g-sensitivity) of 0.1 ppb/g
  • 50kg shock and 70g vibration resistance
  • 500 million hours MTBF
