The SY58021U 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 SY58021U can process
clock signals as fast as 4GHz.
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 VT pin. The outputs are 100k
LVPECL compatible, with extremely fast rise/fall times
guaranteed to be less than 100ps.
The SY58021U 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 SY58022U 1:4 fanout buffer with 400mV LVPECL output
swing, or the SY58020U 1:4 CML fanout buffer. The
SY58021U is part of Micrel’s high-speed, Precision Edge
product line.
