The SY58012U 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
less than 10ps
(pk-pk)
total jitter, the SY58012U can process
clock signals as fast as 5GHz or 5Gbps data.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to LVPECL, LVDS
or CML differential signals, (AC-coupled 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
100k LVPECL compatible, with extremely fast rise/fall times
guaranteed to be less than 110ps.
The SY58012U 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 faster rise/fall times, or greater bandwidth, consider
the SY58013U 1:2 fanout buffer with 400mV output swing,
or the SY58011 1:2 CML (400mV) fanout buffer. The
SY58012U is part of Micrel’s high-speed, Precision Edge
product line. Data sheets and support documentation can
be found on Micrel’s web site at www.micrel.com.
