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
differential
termination resistor networks in the signal path.
differential input can also accept AC-coupled LVPECL
and LVDS signals. Input voltages as small as 200mV
(400mV
transmission line. For AC-coupled input interface
applications, an internal voltage reference is provided to
bias the V
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
