Device Overview

Summary

The SY58037U 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 SY58037U distributes clock frequencies from DC to 4GHz and data rates to 5Gpbs guaranteed over temperature and voltage.The SY58037U 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 SY58037U features a patent-pending isolation design that significantly improves channel-to-channel crosstalk performance.The SY58037U 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 SY58037U is part of Micrel's high-speed, Precision Edge® product line.
