Device Overview

Summary

The SY89859U is a low jitter, low-power, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY89859U distributes clock frequencies from DC to >2.5GHz, and data rates to 2.5Gbps guaranteed over temperature and voltage.The SY89859U 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 level shifting or termination resistor networks in the signal path. The outputs are 800mV, 100K-compatible LVPECL with extremely fast rise/fall time guaranteed to be less than 180ps.The SY89859U features a patent-pending isolation design that significantly improves on channel-to-channel crosstalk-induced jitter performance.The SY89859U 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 SY89859U is part of Micrel's high-speed, Precision Edge® product line.
