Product details
The DSC1001CI2-074.2500B from Microchip Technology 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 74.25 MHz with seawater-resistant outputs, the solution meets the stringent requirements of autonomous underwater vehicle (AUV) sonar arrays.Standby (Power Down) 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 1.8V ~ 3.3V 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.Rated for -40°C ~ 85°C operation, the device withstands thermal vent proximity in hydrothermal vent exploration.The 8.7mA ultra-low power consumption enables multi-year deployment in deep-sea observatories.Compliant with AEC-Q100 standards, the device undergoes hyperbaric chamber testing to 12,000 psi.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 0.126" L x 0.098" W (3.20mm x 2.50mm) compact form factor, the oscillator fits within ROV (Remotely Operated Vehicle) instrumentation pods.The 0.035" (0.90mm) hydrodynamic profile minimizes drag in underwater glider applications.
