High Temp.

SiTime’s automotive (AEC-Q100) and high-temperature oscillators deliver ±20 ppm frequency stability from -55 °C to 125°C. They are 2 times better in stability, 20 times more reliable, and 30 times more resistant to shock and vibration compared to quartz.
• 1 to 137 MHz with 6 decimal places of accuracy
• Military (-55 to 125 °C), automotive (-40 to 125 °C), extended industrial (-40 to 105 °C) temperatures
• Low vibration sensitivity (g-sensitivity) of 0.1 ppb/g
• 50,000 g shock and 70 g vibration resistance
• 500 million hours MTBF
