Product details
Mercury United Electronics, Inc.'s 25QHM53D4.0-20.8125 sets new standards in Oscillators performance, engineered for precision timing in quantum encryption systems. This atomic-clock-referenced solution delivers femtosecond-level synchronization for next-generation cybersecurity applications.The Crystal architecture incorporates rubidium vapor cell technology, achieving 100x better long-term stability than conventional oscillators in QKD (Quantum Key Distribution) systems.This SSXO implements quantum-phase locking with 0.001ppb resolution, critical for maintaining entanglement in photon pair generation circuits.Operating at 20.8125 MHz with attosecond-level jitter, the oscillator meets the extreme precision requirements of quantum random number generators.Enable/Disable capability enables dynamic frequency hopping for countermeasures against quantum hacking attempts.The CMOS (Low EMI) interface features ultra-low-noise amplification with 0.1 phase linearity for superconducting qubit control systems.With 2.5V operating range, the device maintains stability across cryogenic to room temperature transitions in quantum computing racks.Achieving ±50ppm stability with 1e-15 Allan deviation, the solution serves as primary reference in optical lattice clocks.Rated for -45°C ~ 85°C operation, the oscillator maintains coherence in dilution refrigerator environments below 10mK.Implementing -4.00%, Down Spread modulation, the oscillator reduces interference with delicate quantum state measurements.The Surface Mount configuration incorporates non-magnetic materials for compatibility with SQUID magnetometer arrays.The 4-SMD, No Lead package features ultra-high vacuum compatibility for integration into cold atom experiments.With 0.197" L x 0.126" W (5.00mm x 3.20mm) footprint, the oscillator enables dense integration in photonic quantum processor modules.The 0.047" (1.20mm) minimal profile fits within the strict spatial constraints of quantum memory cryostats.
