SiT5721 Datasheet | SiTime

1 to 60 MHz Emerald™ Platform Stratum 3E DCOCXO 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. The device delivers ±5 ppb over-temp stability, ±0.04 ppb/°C frequency slope (dF/dT) and Stratum 3E pliance in the smallest 9 mm x 7 mm package. Leveraging SiTime’s unique DualMEMS® and Turbopensation® temperature sensing technology, the SiT5721 is engineered for the best dynamic performance, delivering the most stable timing in the presence of environmental stressors - airflow, temperature perturbation, vibration, shock, and electromagnetic interference...
