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 only
116fsRMS phase 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- 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 VT pin. The outputs are optimized
to drive 400mV typical swing into 50ohms loads, with
extremely fast rise/fall times guaranteed to be under 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
