Device Overview

Summary

The SY89474U is a 2.5V precision, high-speed 2:1 differential MUX capable of processing clocks up to 2.5GHz and data up to 2.5Gbps.The differential input includes Micrel's unique, 3-pin input termination architecture that directly interfaces 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 output is 325mV LVDS with fast rise/fall times guaranteed to be less than 150ps.The SY89474U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89474U is part of Micrel's highspeed, Precision Edge® product line. For multiple clock switchover solutions, please refer to the SY89840U - SY89845U family.
