The patented SXO-75 is the industry’s first smart Crystal clock, integrating complex synchronization functionality all in one low-cost, ultra-small package. It utilizes SmarTiming+® technology to provide a host of timing features, which were previously implemented externally on a separate circuit board. The SXO intelligently synchronizes, disciplines, and controls any Stratum-1 reference such as GPS, Cesium, Hydrogen Maser, and T1/E1 at cutting-edge 1 ns resolution.
