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).
The environmental robustness of SiT5721 enables unmatched ease-of-use and simplifies system design:
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.
