1至60 MHz,Stratum 3e Dcocxo

The SiT5721 is the industry’s smallest Stratum 3E digitally controlled 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 DCOCXO delivers the most stable timing in the presence of environmental stressors such as airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

SIT5721的环境稳健性使能无与伦比的易用性和简化系统设计:

  • 可以放在PCB上的任何地方
  • No mechanical cover or shielding needed for thermal isolation
  • 无需外部监管机构
  • 高湿度环境不需要额外的密封

The SiT5721 can be factory-programmed to any frequency between 1 and 60 MHz. In addition to industry leading performance, the DCOCXO is offered in a 9 x 7 mm package, the smallest Stratum 3E OCXO available.
