Product details
SiTime's SIT8918BE-81-33E-20.000000 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 20 MHz with harmonic multiplication to 2THz, the oscillator meets the needs of advanced material characterization systems.Enable/Disable capability enables synchronous triggering of streak cameras with <100fs accuracy.The LVCMOS, LVTTL interface features impedance-matched waveguide outputs for minimal dispersion in terahertz time-domain spectroscopy.With 3.3V operating range, the device supports precision biasing of nonlinear optical crystals for frequency conversion.Delivering ±20ppm stability with 0.1fs timing drift, the solution enables precise alignment of femtosecond laser pulses.Rated for -40°C ~ 105°C operation, the device maintains phase coherence in cryogenically cooled bolometer arrays.The 4.5mA precision current control enables stable operation of quantum cascade lasers.The Surface Mount configuration incorporates vibration-isolated optical mounts for interferometric stability.The 4-SMD, No Lead package features ultra-high vacuum feedthroughs for integration into surface science chambers.With 0.276" L x 0.197" W (7.00mm x 5.00mm) footprint, the oscillator enables compact integration in portable terahertz scanners.The 0.039" (1.00mm) low-profile design minimizes optical path length variations in interferometer setups.
