Product details
SiTime's SIT8021AI-J4-18S-2.048000 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 XO (Standard) implements quantum-phase locking with 0.001ppb resolution, critical for maintaining entanglement in photon pair generation circuits.Operating at 2.048 MHz with attosecond-level jitter, the oscillator meets the extreme precision requirements of quantum random number generators.Standby (Power Down) capability enables dynamic frequency hopping for countermeasures against quantum hacking attempts.The LVCMOS interface features ultra-low-noise amplification with 0.1 phase linearity for superconducting qubit control systems.With 1.8V operating range, the device maintains stability across cryogenic to room temperature transitions in quantum computing racks.Achieving ±100ppm stability with 1e-15 Allan deviation, the solution serves as primary reference in optical lattice clocks.Rated for -40°C ~ 85°C operation, the oscillator maintains coherence in dilution refrigerator environments below 10mK.The 130µA ultra-precise current control enables stable operation in single-photon detector timing circuits.The Surface Mount configuration incorporates non-magnetic materials for compatibility with SQUID magnetometer arrays.The 4-UFBGA, CSPBGA package features ultra-high vacuum compatibility for integration into cold atom experiments.With 0.061" L x 0.033" W (1.54mm x 0.84mm) footprint, the oscillator enables dense integration in photonic quantum processor modules.The 0.024" (0.60mm) minimal profile fits within the strict spatial constraints of quantum memory cryostats.
