1到60 MHz, Stratum 3E OCXO

The SiT5711 is the industry’s smallest Stratum 3E OCXO with ±5 ppb frequency stability and 40 ppt/°C frequency slope (ΔF/ΔT). This device is engineered to provide the best dynamic performance. Leveraging SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology, this OCXO delivers the most stable timing in the presence of environmental stressors such as airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

The environmental robustness of SiT5711 enables unmatched ease-of-use and simplifies system design:

  • Can be placed anywhere on the PCB
  • No mechanical cover or shielding needed for thermal isolation
  • No external regulators required
  • 高湿度环境不需要额外的密封

The SiT5711 can be factory-programmed to any frequency between 1 and 60 MHz and the 9 x 7 mm package is the smallest Stratum 3E OCXO available.
