SiT-515x Elite Platform™ Super-TCXOs

SiTime SiT-515x Elite Platform™ Super-TCXOs deliver stable timing in the presence of environmental stressors like air flow, temperature perturbation, vibration, shock, and electromagnetic interference. These TCXOs leverage SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology. The SiT5155 TCXOs are engineered for high-accuracy GNSS systems in precision farming, survey, construction, and other industrial equipment. The SiT5156 and SiT5157 TCXOs are highly flexible, tight-stability oscillators capable of supporting up to 220MHz. The Elite Platform™ Super-TCXOs are ideal for high-reliability telecom, wireless and networking, industrial, precision GNSS, and audio/video applications.
