Precision MHz Super-TCXOs

SiTime MEMS precision oscillators deliver the most stable timing under environmental stressors – airflow, rapid temperature change, shock, vibration, poor power supply, and EMI – in a small, robust package. These devices can be programmed to any combination of frequency, stability, voltage, and pull range within a wide range of parameters, eliminating the long lead times, customization costs, and reliability concerns associated with quartz TCXOs and OCXOs.

Super-TCXOs

Elite Platform® and Elite X Super-TCXOs are precision timing solutions with exceptional dynamic performance and rich features. These devices solve deep-rooted timing problems for telecom, networking, edge synchronization, and precision GNSS systems. By combining tight-stability with the robust package of a ceramic TCXO, SiTime Super-TCXOs replace legacy quartz OCXOs while increasing reliability, lowering power, and reducing size.

  • Tight stability (±0.01 ppm to ±2.5 ppm), 1 to 220 MHz
  • Better dynamic stability than quartz (±0.5 ppb/°C ΔF/ΔT), resistant to airflow and thermal shock
  • -40°C to 105°C operation uniquely enables fan-less outdoor equipment
  • Lower power consumption (110 mW, 2.5V) for battery-operated edge equipment
  • I2C digital frequency tuning eliminates external DAC and sensitivity to board noise
  • On-chip power supply noise filtering eliminates dedicated LDO
