MEMS Clock Generators

Cascade Platform MEMS-based Clock Generator Package

MEMS Clock Generators

Chorus™ Automotive Clock Generators orchestrate complex timing for automotive compute and sensor systems by providing up to four configurable differential or up to eight single-ended low skew outputs. FailSafe™ technology enables ease of functional safety design by providing programmable end-to-end safety monitors. They are PCIExpress (PCIe) Generations 1 - 6 compliant, with spread-spectrum options, on-chip regulators for extremely good power supply noise rejection, and phase-configurable and programmable skew outputs.

  • Higher Performance: Up to 10X better resilience with integrated MEMS resonator.
  • Features to enable functional safety: Built-in programmable fault monitors.
  • Eliminates common issues such as noise coupling and impedance matching
  • Smaller Footprint: up to 50% less board space
  • Always-reliable startup across -40 to 125°C and in other harsh environmental conditions
  • No activity dips/frequency jumps inherent with quartz.
