The SY89852UMG TR is a 2.5V/3.3V precision, high-speed, 2:1 differential MUX capable of handling clocks up to 2.5GHz and data streams up to 2.5Gbps.The differential input includes Micrel's unique, patent pending 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 unique, patent input isolation design minimizes crosstalk minimizing crosstalk induced jitter. The outputs are 800mV LVPECL, with extremely fast rise/fall time guaranteed to be less than 180ps.The SY89852UMG TR 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 SY89852UMG TR is part of Micrel's high-speed, Precision Edge® product line.
