Features and Applications

The SY58031UMG TR is a 2.5 V/3.3 V precision, high-speed, fully differential CML 1:8 fanout buffer. The device optimized to provide eight identical output copies with less than 20ps of skew and less than 10psPP total jitter and can process clock signals as fast as 6 GHz

The differential input includes unique, 3-pin input termination architecture that allows to directly interface to CML, LVPECL, and LVDS differential signals (AC- or DC-coupled) without any level-shifting or termination resistor networks in the signal path.The SY58031U operates from a 2.5 V ±5% supply or 3.3 V ±10% supply and is guaranteed over the full industrial temperature range (–40°C to +85°C).
