SiTime Corporation Stratum 3E DCOCXOs SIT5721AC-KW133-T-40.000000

The SiT5721 is a Stratum 3E compliant digitally controlled oven-controlled crystal oscillator (DCOCXO) designed for 1 to 60 MHz applications, offering ±5 ppb frequency stability over temperature and ±0.04 ppb/°C frequency slope. It features I²C interface for ±5 ppt resolution frequency tuning with up to ±10 ppm pull range, operates from a 3.3 V supply, and supports LVCMOS or clipped sinewave output. Housed in a 9 mm × 7 mm package, it provides exceptional dynamic stability under environmental stressors including airflow, vibration, and EMI, with an Allan deviation of 1.4E-11 at 10 seconds. The part is rated for industrial temperature range (-40°C to 85°C) and includes integrated power supply noise filtering.
