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 to 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).
The SiT5501 can be factory-programmed to any combination of frequency, voltage, and pull range. This programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency is custom built.
