The Elite X™ SiT5501 is a ±10 ppb Stratum 3E precision oscillator. Engineered for exceptional dynamic performance, this MEMS-based Super-TCXO is ideal for replacing larger and less robust quartz mini-OCXOs in edge networks. The SiT5501 is 2x smaller, 4x lower power and 30x more reliable than comparable mini-OCXOs while being fully compliant with the GR-1244 Stratum 3E oscillator specifications. By leveraging SiTime’s unique DualMEMS® and TurboCompensation® temperature sensing technology, the SiT5501 delivers the most stable timing in the presence of environmental stressors – airflow, temperature perturbation, vibration, shock and electromagnetic interference (EMI).
