Product details
The SIT3521AI-1C233-3Y50.000000Y by SiTime redefines Oscillators technology, specifically engineered for extreme-radiation environments in nuclear power monitoring systems. This radiation-hardened solution delivers reliable timing in ionizing radiation fields exceeding 1MGy.Featuring MEMS technology with sapphire insulation, the device maintains <1ppm frequency deviation after 10 years of continuous gamma exposure in reactor vessel instrumentation.As a DCXO, this oscillator implements triple-modular redundancy with <1ms failover time, critical for safety-critical nuclear control systems.Operating at 50 MHz with radiation-induced phase error correction, the solution meets IEC 61508 SIL 3 requirements for reactor protection systems.Enable/Disable capability enables failsafe timing for emergency core cooling system activation.The LVPECL configuration includes fiber-optic isolation for noise immunity in high-electromagnetic-interference containment buildings.With 3.3V operating range, the device maintains operation during station blackout scenarios with backup power fluctuations.Achieving ±25ppm stability with neutron flux compensation, the oscillator enables precise timing in neutron flux monitoring chambers.The ±780ppm programmability allows real-time adjustment for Doppler broadening effects in reactor core analysis.Rated for -40°C ~ 85°C operation, the device withstands LOCA (Loss-of-Coolant Accident) steam conditions.The 93mA radiation-hardened design ensures stable operation in spent fuel pool monitoring systems.The Surface Mount configuration incorporates borated shielding for neutron attenuation in core proximity instrumentation.The 10-VQFN Exposed Pad package features zirconium alloy encapsulation for corrosion resistance in primary coolant loops.With 0.197" L x 0.126" W (5.00mm x 3.20mm) compact form factor, the oscillator fits within robotic inspection crawlers for reactor pressure vessels.The 0.035" (0.90mm) low-profile design enables installation in fuel rod gap monitors.
