The SRO-5680 is a new, slim, ultra-low-noise GPS/GNSS-disciplined rubidium oscillator (GPSDO) featuring EMI-shielded rugged packaging and advanced synchronization capabilities in a compact, cost-effective design. Compatible with the FEI-5680 Rb model, it employs SmarTiming+® technology to synchronize, discipline, and control any primary 1PPS reference signal—including GPS/GNSS, Cesium, Hydrogen Maser, and T1/E1—with 1ns resolution.
Engineered for demanding applications such as next-generation SATCOM, airborne systems, and stringent military environments, it delivers exceptional phase noise performance, stability, and holdover accuracy.
