Description
The new, slim, ultra low noise SRO-5680 GPS/GNSS-disciplined rubidium oscillator (GPSDO) features an EMI-shielded, rugged packaging, while integrating complex synchronization functionality all in one low-cost, super-small package.
It is compatible with the FEI-5680 Rb model and utilizes the SmarTiming+® technology to provide a host of integrated GPS/GNSS disciplining and timing features. The SRO intelligently synchronizes, disciplines, and controls any primary 1PPS reference signal, such as GPS/GNSS, Cesium, Hydrogen Maser, and T1/E1, at cutting-edge 1ns resolution. Its slim and rugged packaging and ultra low noise features make it greatly suitable for next gen SATCOM, airborne and other stringent MIL applications.
