General Description
The SY58022U 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 15 ps
of skew and less than 10 ps
PP total jitter, the
SY58022U can process clock signals as fast as
5.5 GHz.
The differential input includes Microchip’s unique, 3-pin
input termination architecture interfaces to differential
LVPECL, CML, and LVDS signals (AC- or DC-coupled)
as small as 100 mV 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 400 mV LVPECL
compatible with extremely fast rise/fall times ensured to
be less than 80 ps.
The SY58022U operates from a 2.5V ±5% supply or
3.3V ±10% supply and is ensured over the full industrial
temperature range (–40°C to +85°C). For applications
that require greater output swing or CML compatible
outputs, consider the SY58021U 1:4 fanout buffer with
LVPECL outputs, or the SY58020U 1:4 fanout buffer
with 400 mV CML outputs.
