The SY89850U is a 2.5V/3.3V precision, high-speed, differential receiver capable of handling clocks up to 4GHz and data streams up to 3.2Gbps.The differential input includes Micrel's unique, 3-pin input termination architecture that allows users 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 800mV LVPECL, with extremely fast rise/fall times guaranteed to be less than 160ps.The SY89850U 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 SY89850U is part of Micrel's high-speed, Precision Edge® product line.
