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 ±25 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 than quartz. They enable higher system performance and fewer failures in harsh environments.

Key Features:

  • 1 to 110 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
