Product details
SiTime's SIT3373AC-4B2-28NX644.531250 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 VCXO implements attosecond-level synchronization with <10fs RMS jitter, critical for pump-probe experiments in ultrafast physics.Operating at 644.53125 MHz with harmonic multiplication to 2THz, the oscillator meets the needs of advanced material characterization systems.The HCSL interface features impedance-matched waveguide outputs for minimal dispersion in terahertz time-domain spectroscopy.With 2.8V operating range, the device supports precision biasing of nonlinear optical crystals for frequency conversion.Delivering ±25ppm stability with 0.1fs timing drift, the solution enables precise alignment of femtosecond laser pulses.The ±370ppm tuning capability supports dynamic compensation for atmospheric dispersion in free-space terahertz communications.Rated for -20°C ~ 70°C operation, the device maintains phase coherence in cryogenically cooled bolometer arrays.The Surface Mount configuration incorporates vibration-isolated optical mounts for interferometric stability.The 6-SMD, No Lead package features ultra-high vacuum feedthroughs for integration into surface science chambers.With 0.126" L x 0.098" W (3.20mm x 2.50mm) footprint, the oscillator enables compact integration in portable terahertz scanners.The 0.031" (0.80mm) low-profile design minimizes optical path length variations in interferometer setups.
