General Description

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 27fs
of typical additive phase jitter, the SY58020U
can process clock signals as fast as 6GHz.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that 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 (V
) is provided to bias the V
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.
