Product details
The SIT3373AI-1B3-28NY644.531250 from SiTime represents a paradigm shift in Oscillators technology, optimized for extreme-environment timing in deep-sea exploration systems. This pressure-compensated oscillator delivers reliable performance at ocean depths exceeding 10,000 meters.Featuring MEMS technology with hydrostatic pressure compensation, the device maintains <0.1ppm frequency deviation at 1,100 atmosphere pressures in submersible navigation systems.As a VCXO, this oscillator incorporates titanium housing with <0.01% creep deformation, ensuring long-term stability in permanent seafloor monitoring stations.Operating at 644.53125 MHz with seawater-resistant outputs, the solution meets the stringent requirements of autonomous underwater vehicle (AUV) sonar arrays.The LVPECL configuration implements high-impedance seawater isolation, preventing signal degradation in submerged sensor networks.With 2.8V operating range, the device supports power-efficient operation from benthic microbial fuel cells.Achieving ±50ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.The ±745ppm programmability allows compensation for sound velocity changes in varying salinity conditions.Rated for -40°C ~ 85°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The Surface Mount design incorporates pressure-balanced oil-filled cavities for equalization at extreme depths.The 6-SMD, No Lead package features marine-grade corrosion resistance for saltwater immersion up to 30 years.With 0.126" L x 0.098" W (3.20mm x 2.50mm) compact form factor, the oscillator fits within ROV (Remotely Operated Vehicle) instrumentation pods.The 0.031" (0.80mm) hydrodynamic profile minimizes drag in underwater glider applications.
