General Description
The SY89851U is a low jitter, low skew, high-speed
1:2 differential fanout buffer optimized for precision
telecom
and
enterprise
server
distribution
applications.
The
SY89851U
distributes
clock
frequencies from DC to >3GHz, and data rates to
2.5Gbps guaranteed over temperature and voltage.
The SY89851U 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 800mV, 100K-
compatible LVPECL with extremely fast rise/fall time
guaranteed to be less than 180ps.
The SY89851U 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
SY89851U is part of Micrel's high-speed, Precision
Edge
product line.
