General Description
The SY56011R is a fully differential, low voltage
1.2V/1.8V/2.5V CML 1:2 Fanout Buffer with input
equalization. The SY56011R can process clock signals
as fast as 4.5 GHz or data patterns up to 6.4Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination
architecture
that
interfaces
to
CML
differential
signals,
without
any
level-shifting
or
termination resistor networks in the signal path.
The
differential input can also accept AC-coupled LVPECL
and LVDS signals. Input voltages as small as 200mV
(400mVpp) are applied before the 9”, 18” or 27” FR4
transmission
line.
For
AC-coupled
input
interface
applications, an internal voltage reference is provided to
bias the VT pin. The outputs are CML, with extremely
fast rise/fall times guaranteed to be less than 80ps.
The SY56011R operates from a 2.5V ±5% core supply
and a 1.2V, 1.8V or 2.5V ±5% output supply and is
guaranteed over the full industrial temperature range
(–40°C to +85°C). The SY56011R is part of Micrel’s
high-speed, Precision Edge
product line.
