SY89858U
Precision Low Power 1:8 LVPECL Fanout
Buffer with Internal Termination
General Description
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 10ps
pp
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 50
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. All support documentation can be found
on Micrel’s web site at: www.micrel.com.
