Product details
The SIT8918BE-11-18E-25.000000 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 25 MHz with seawater-resistant outputs, the solution meets the stringent requirements of autonomous underwater vehicle (AUV) sonar arrays.Enable/Disable capability enables sleep-mode timing for energy-efficient tsunami warning buoys.The LVCMOS, LVTTL configuration implements high-impedance seawater isolation, preventing signal degradation in submerged sensor networks.With 1.8V operating range, the device supports power-efficient operation from benthic microbial fuel cells.Achieving ±20ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.Rated for -40°C ~ 105°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The 4mA 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-SMD, No Lead package features marine-grade corrosion resistance for saltwater immersion up to 30 years.With 0.098" L x 0.079" W (2.50mm x 2.00mm) 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.
