The Transmission Control Unit (TCU) monitors and controls the operation of the vehicle’s automatic transmission. Input from multiple sensors is processed to optimally select gears to achieve improved engine emissions, fuel consumption, stable handling, and gear shift system reliability. Our automotive-grade MEMS oscillators replace the traditional quartz crystal/oscillator to provide a robust and highly stable clock signal across the automotive grade 1 temperature range.

Key Benefits

  • High reliability: AEC-Q100
  • Excellent frequency stability over temperature: ±25 ppm at (−40 to +125°C) (Grade 1)
  • 500 times better shock and five times better vibration resistance than quartz
  • Smallest package size: 1.6 × 1.2 mm
