Product details
The SIT3372AC-1B2-25NG148.425750 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 148.42575 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 2.5V operating range, the device supports power-efficient operation from benthic microbial fuel cells.Achieving ±25ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.The ±120ppm programmability allows compensation for sound velocity changes in varying salinity conditions.Rated for -20°C ~ 70°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The 92mA ultra-low power consumption enables multi-year deployment in deep-sea observatories.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.
