The SY58037UMI-TR is a low jitter, low skew, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY58037UMI-TR distributes clock frequencies from DC to 4GHz and data rates to 5Gpbs guaranteed over temperature and voltage.The SY58037UMI-TR 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 outputs are 50Ω source-terminated CML with extremely fast rise/fall time guaranteed to be less than 70ps.The SY58037UMI-TR features a patent-pending isolation design that significantly improves channel-to-channel crosstalk performance.The SY58037UMI-TR operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY58037UMI-TR is part of Micrel's high-speed, Precision Edge® product line.
