General Description
The SY89854U 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 20ps of skew and less than 10ps(pp)
total jitter, the SY89854U can process clock signals
as fast as 2GHz.
The differential input includes Micrel’s unique, patent
pending 3-pin input termination architecture that
interfaces to any differential signal (AC or DC-
coupled) as small as 100mV (200mVpp) 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 center-tap (VT)
pin.
The outputs are 800mV LVPECL, with fast
rise/fall times guaranteed to be less than 180ps.
The SY89854U operates from a 2.5V ±5% supply or
a 3.3V ±10% supply and is guaranteed over the full
industrial temperature range of –40°C to +85°C.
The SY89854U is part of Micrel’s high-speed,
Precision Edge
product line.
