Product details
The CMX309FBC14.31818MTR from Citizen Finedevice Co Ltd 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 XO (Standard), this oscillator incorporates titanium housing with <0.01% creep deformation, ensuring long-term stability in permanent seafloor monitoring stations.Operating at 14.31818 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 configuration implements high-impedance seawater isolation, preventing signal degradation in submerged sensor networks.With 3.3V operating range, the device supports power-efficient operation from benthic microbial fuel cells.Achieving ±100ppm stability with pressure-induced error correction, the oscillator enables precise positioning in deep-ocean seismology.Rated for -20°C ~ 70°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The 9mA 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-SOJ, 5.08mm pitch package features marine-grade corrosion resistance for saltwater immersion up to 30 years.With 0.547" L x 0.341" W (13.90mm x 8.65mm) compact form factor, the oscillator fits within ROV (Remotely Operated Vehicle) instrumentation pods.The 0.185" (4.70mm) hydrodynamic profile minimizes drag in underwater glider applications.
