The SY58020U is a 2.5V/3.3V precision, high-speed, fully
differential 1:4 CML fanout buffer. Optimized to provide four
identical output copies with less than 15ps of skew and less
than 10ps
(pk-pk)
total jitter, the SY58020U can process clock
signals as fast as 6GHz.
The differential input includes Micrel’s unique, 3-pin input
termination architecture interfaces to differential LVPECL,
LVDS, and CML 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
optimized to drive 400mV typical swing into 50
loads, with
extremely fast rise/fall times guaranteed to be less than
60ps.
The SY58020U 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 LVPECL outputs, consider the SY58021U or
SY58022U 1:4 fanout buffer with 800mV and 400mV output
swing, respectively. The SY58020U 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
