General Description
The SY56020XR is a fully differential, low voltage
1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with input
equalization.
The SY56020XR can process clock
signals as fast as 4.5GHz or data patterns up to
6.4Gbps.
The differential input includes Micrel’s unique 3-pin input
termination architecture that interfaces to DC-coupled
2.5V/3.3V LVPECL, 1.2V/1.8V/2.5V CML or LVDS
differential signals. For AC-coupled input applications,
an internal voltage reference is provided for input bias.
Input voltages as small as 200mV (400mVpp) are applied
before the 9, 18 or 27-inch FR4 transmission line. The
outputs are CML.
The SY56020XR 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 SY56020XR is part of Micrel’s
high-speed, Precision Edge
product line.
