The SY58013U is a 2.5V/3.3V precision, high-speed, fully
differential 1:2 LVPECL fanout buffer. Optimized to provide
two identical output copies with less than 15ps of skew and
only 55fsRMSphase jitter, the SY58013U can process clock
signals as fast as 6GHz or data patterns up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to LVPECL, LVDS,
and CML differential 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 (VREF-
AC) is provided to bias the VTpin. The outputs are 400mV
LVPECL compatible, with extremely fast rise/fall times
guaranteed to be less than 80ps.
The SY58013U 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 SY58012U 1:2 fanout buffer with 800mV
LVPECL outputs, or the SY58011U 1:2 fanout buffer with
400mV CML outputs. The SY58013U is part of Micrel’s
high-speed, Precision Edge® product line. Datasheets and
support documentation can be found on Micrel’s web site at
