SiT5721 Datasheet (SiTime) - Platform Stratum 3E DCOCXO

SiT5721, Platform Stratum 3E DCOCXO

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 compliance in the smallest 9 mm x 7 mm p
