Improve System Performance

SiTime MEMS-based products deliver higher performance in areas critical to the performance and operation of the system.

  • Better Frequency Stability over Temperature
    SiTime offers both TCXOs (temperature compensated oscillators) with 0.1 to 5 PPM frequency stability and XOs (oscillators) with 10 to 50 PPM frequency stability. Typical quartz XOs have 25 to 100 PPM stability. Since SiTime XOs and TCXOs have built-in temperature compensation, they are extremely stable over the entire temperature range. More
  • Lower Phase Noise and Jitter
    SiTime’s Encore products offer 500 femtoseconds (typical) and 1 ps (maximum) RMS phase jitter integrated from 12 kHz to 20 MHz. No other MEMS oscillator offers this level of performance. More
  • Superior Resilience
    SiTime oscillators are the most reliable oscillators on the market. With <2 FIT, SiTime XOs are twice as good as other silicon-based oscillators and 13 to 40x more reliable than quartz. Additionally, the performance of SiTime XOs holds up better in noisy, harsh environments. More


Best and Broadest Timing Portfolio

With a rich feature set combined with higher performance, SiTime has the best and broadest timing portfolio available. SiTime pin-compatible oscillators are an easy low-cost drop-in replacement for quartz devices.
