The SY89856U is a 2.5V/3.3V precision, high-speed, 1:6 fanout capable of handling clocks up to 2.0GHz. A differential 2:1 MUX input is included for redundant clock switchover applications.The differential input includes Micrel's unique, 3-pin input termination architecture that allows the device to interface to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The outputs are LVPECL (100k, temperature compensated), with extremely fast rise/fall times guaranteed to be less than 200ps.The SY89856U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89856U is part of Micrel's high-speed, Precision Edge® product line.
