Product details
The 25QHM53D4.0-42.53976 from Mercury United Electronics, Inc. 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 Crystal technology with hydrostatic pressure compensation, the device maintains <0.1ppm frequency deviation at 1,100 atmosphere pressures in submersible navigation systems.As a SSXO, this oscillator incorporates titanium housing with <0.01% creep deformation, ensuring long-term stability in permanent seafloor monitoring stations.Operating at 42.53976 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 CMOS (Low EMI) 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 ±50ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.Rated for -45°C ~ 85°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.Implementing -4.00%, Down Spread modulation, the oscillator reduces acoustic interference with marine life monitoring systems.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 0.197" L x 0.126" W (5.00mm x 3.20mm) compact form factor, the oscillator fits within ROV (Remotely Operated Vehicle) instrumentation pods.The 0.047" (1.20mm) hydrodynamic profile minimizes drag in underwater glider applications.
