Product details
SiTime's SIT3373AI-4B3-28NU644.531250 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 MEMS architecture incorporates rubidium vapor cell technology, achieving 100x better long-term stability than conventional oscillators in QKD (Quantum Key Distribution) systems.This VCXO implements quantum-phase locking with 0.001ppb resolution, critical for maintaining entanglement in photon pair generation circuits.Operating at 644.53125 MHz with attosecond-level jitter, the oscillator meets the extreme precision requirements of quantum random number generators.The HCSL interface features ultra-low-noise amplification with 0.1 phase linearity for superconducting qubit control systems.With 2.8V 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.The ±3145ppm tuning range supports compensation for gravitational time dilation effects in satellite-based quantum communication.Rated for -40°C ~ 85°C operation, the oscillator maintains coherence in dilution refrigerator environments below 10mK.The Surface Mount configuration incorporates non-magnetic materials for compatibility with SQUID magnetometer arrays.The 6-SMD, No Lead package features ultra-high vacuum compatibility for integration into cold atom experiments.With 0.126" L x 0.098" W (3.20mm x 2.50mm) footprint, the oscillator enables dense integration in photonic quantum processor modules.The 0.031" (0.80mm) minimal profile fits within the strict spatial constraints of quantum memory cryostats.
