General Description
The SY58031U is a 2.5V/3.3V precision, high-speed, fully
differential CML 1:8 fanout buffer. The SY58031U is
optimized to provide eight identical output copies with less
than 20ps of skew and only 75fsRMS phase jitter. It can
process clock signals as fast as 6GHz.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows the SY58031U to
directly interface to CML, LVPECL, and LVDS differential
signals (AC- or DC-coupled) without any level-shifting or
termination resistor networks in the signal path. The result
is a clean, stub-free, low-jitter interface solution. The CML
outputs feature 400mV typical swing into 50Ω loads and
provide an extremely fast rise/fall time guaranteed to be
less than 60ps.
The SY58031U operates from a 2.5V ±5% supply or 3.3V
±10% supply and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications that
require high-speed 1:8 LVPECL fanout buffers, consider
the SY58032U and SY58033U. The SY58031U is part of
Micrel’s high-speed, Precision Edge product line.
