Description
General part information
SY89858U Series
The SY89858U is a 2.5V/3.3V precision, high-speed, fully differential LVPECL 1:8 fanout buffer optimized to provide eight identical output copies with less than 30ps of skew and less than 10pspp total jitter. It can process clock signals as fast as 2.0GHz.The differential input includes Micrel's unique, 3-pin input termination architecture that allows the SY89858U to directly interface to LVPECL, CML, and LVDS differential signals (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The result is a clean, stub-free, low-jitter interface solution. The LVPECL (100k temperature compensated) outputs feature 800mV typical swing into 50Ω loads, and provide fast rise/fall times guaranteed to be less than 200ps.The SY89858U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. For applications that require a higher speed fanout buffer, consider the SY58032U. The SY89858U is part of Micrel's high-speed, Precision Edge® product line.
