The SY58022U is a 2.5V/3.3V precision, high-speed, fully
differential 1:4 LVPECL fanout buffer. Optimized to provide
four identical output copies with less than 15ps of skew and
less than 10ps
PP total jitter, the SY58022U can process clock
signals as fast as 5.5GHz.
The differential input includes Micrel’s unique, 3-pin input
termination architecture interfaces to differential LVPECL,
CML, and LVDS signals (AC- or DC-coupled) as small as
100mV without any level-shifting or termination resistor
networks in the signal path. For AC-coupled input interface
applications, an on-board output reference voltage (V
REF-AC) is
provided to bias the V
T pin. The outputs are 400mV LVPECL
compatible, with extremely fast rise/fall times guaranteed to
be less than 80ps.
The SY58022U 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 greater output swing or CML compatible outputs,
consider the SY58021U 1:4 fanout buffer with LVPECL
outputs, or the SY58020U 1:4 fanout buffer with 400mV
CML outputs. The SY58022U is part of Micrel’s high-speed,
Precision Edge product line. All data sheets and support
documentation can be found on Micrel’s web site at: www.
