4pin

The SiT8918 provides an unique combination of high frequency (up to 110 MHz), excellent stability (±25 PPM) and high temperature (up to 125°C) that are not easily available from quartz. This device also features the industry's best G-sensitivity, and shock and vibration resistance.

The SiT8918 comes in industry standard packages and footprints, and therefore replaces quartz without any design changes.

Features Benefits
  • +/-25PPM over automotive temp (-40 to 125 °C)
  • Better timing margin ideal for outdoor and high temp operating environment
  • 0.1 ppb/g low G-sensitivity
  • Improved system performance under vibration
  • Carrrier drop-test compliance (STB, etc.)
  • 70 g shock and 50 kg vibration
  • Best system relability in harsh environment
  • SoftEdge(TM) configurable drive strength
  • Slower rise/fall time that minimizes EMI from the oscillator
  • Saves cost by driving multiple loads and eliminate additional timing components
  • 5 industry standard package
  • 100% drop in repalcement of quartz VCXO
  • Ultra fast lead time (2 to 4 weeks)
  • Reduce inventory overhead
  • Mitigate shortage risks
