Description
The SiT5721 is the industry’s first digitally controlled OCXO (DCOCXO), enabling output frequency tuning via I2C interface with ±5 ppt (±0.005 ppb) resolution.
Features
- Any frequency between 1 MHz and 60 MHz, in 1 Hz steps.
- ±0.04 ppb/°C frequency slope typical (dF/dT).
- ±5 ppb frequency stability over temperature.
- Up to 85°C operating temperature range.
- 1.4E-11 ADEV at 10 second averaging time.
- Digital frequency pulling via I2C
Up to ±10 ppm pull range ±5 ppt pulling resolution.
- Exceptional dynamic stability under airflow and rapid temperature changes.
- Excellent holdover over a wide range of conditions.
- Integrate.
