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 6.4 Gbps.

The differential input includes a 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 200 mV

(400 mVPP) 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 80 ps.

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 the high

speed, Precision Edge® product line.
