The Endura™ ruggedized SiT5541 is a precision Super-TCXO® with ±10-ppb stability over temperature, from -40°C to 105°C. Engineered for exceptional dynamic performance, this device provides the most stable timing in the presence of environmental stressors such as airflow, temperature perturbation, vibration, shock, and EMI. It delivers ±0.5 ppb/°C typical frequency slope (ΔF/ΔT) and 2e-11 ADEV at 10 second averaging time, and is resistant to shock and vibration with 0.01 ppb/g acceleration sensitivity.
The MEMS-based SiT5541 is ideal for replacing larger and less-robust power-hungry quartz OCXOs in PNT, aerospace-defense networking and communication systems. It is 2x smaller, 10x more resilient, and up to 10x lower power than comparable OCXOs.
The SiT5541 is tested in accordance with MIL-PRF-55310 and MIL-STD-883. It can be factory-programmed to any combination of frequency, voltage, and pull range, enabling designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz products where each frequency is custom-built.
