The SY58038UMI-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 SY58038UMI-TR distributes clock frequencies from DC to 3.5GHz, and data rates to 4.5Gpbs guaranteed over temperature and voltage.The SY58038UMI-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 without any level shifting or termination resistor networks in the signal path. The outputs are 800mV, 100K compatible LVPECL with extremely fast rise/fall times guaranteed to be less than 100ps.The SY58038UMI-TR features a patented isolation design that significantly improves channel-to-channel crosstalk performance. The SY58038UMI-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 SY58038UMI-TR is part of Micrel's high-speed, Precision Edge®product line.
