Features Benefits
  • 100% Silicon die, can be easily integrated inside standard semiconductor packages
  • Eliminate all external clocks.
    • Save board space
    • Simplify design and BOM
    • Simplify sourcing
  • Smallest and thinnest resonator for real time clock and time keeping applications
  • Replaces 32 kHz quartz crystals in space constrained applications
  • Enables ± 5 PPM stability on real time clock
  • Provides very accurate output clock
  • Ultra-stable, virtually zero shift, even after soldering and reflow
