Product details
The SIT1534AC-J5-DCC-00.256 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 XO (Standard), this oscillator incorporates titanium housing with <0.01% creep deformation, ensuring long-term stability in permanent seafloor monitoring stations.Operating at 256 Hz with seawater-resistant outputs, the solution meets the stringent requirements of autonomous underwater vehicle (AUV) sonar arrays.The LVCMOS configuration implements high-impedance seawater isolation, preventing signal degradation in submerged sensor networks.With 1.2V ~ 3.63V operating range, the device supports power-efficient operation from benthic microbial fuel cells.Achieving ±75ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.Rated for -10°C ~ 70°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The 1.3µA 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 4-UFBGA, CSPBGA package features marine-grade corrosion resistance for saltwater immersion up to 30 years.With 0.061" L x 0.033" W (1.54mm x 0.84mm) compact form factor, the oscillator fits within ROV (Remotely Operated Vehicle) instrumentation pods.The 0.024" (0.60mm) hydrodynamic profile minimizes drag in underwater glider applications.
