Product details
SiTime's SIT8021AI-J4-XXS-19.680000 establishes new benchmarks in Oscillators performance, developed for ultra-high-speed timing in terahertz research equipment. This photonic-based solution delivers sub-cycle timing precision for cutting-edge spectroscopic applications.Utilizing MEMS technology with optical frequency comb stabilization, the device achieves 1e-18 fractional frequency stability for molecular clock references.This XO (Standard) implements attosecond-level synchronization with <10fs RMS jitter, critical for pump-probe experiments in ultrafast physics.Operating at 19.68 MHz with harmonic multiplication to 2THz, the oscillator meets the needs of advanced material characterization systems.Standby (Power Down) capability enables synchronous triggering of streak cameras with <100fs accuracy.The LVCMOS interface features impedance-matched waveguide outputs for minimal dispersion in terahertz time-domain spectroscopy.With 2.25V ~ 3.63V operating range, the device supports precision biasing of nonlinear optical crystals for frequency conversion.Delivering ±100ppm stability with 0.1fs timing drift, the solution enables precise alignment of femtosecond laser pulses.Rated for -40°C ~ 85°C operation, the device maintains phase coherence in cryogenically cooled bolometer arrays.The 160µA precision current control enables stable operation of quantum cascade lasers.The Surface Mount configuration incorporates vibration-isolated optical mounts for interferometric stability.The 4-UFBGA, CSPBGA package features ultra-high vacuum feedthroughs for integration into surface science chambers.With 0.061" L x 0.033" W (1.54mm x 0.84mm) footprint, the oscillator enables compact integration in portable terahertz scanners.The 0.024" (0.60mm) low-profile design minimizes optical path length variations in interferometer setups.
