SY56011R Low Voltage Fanout Buffer

The SY56011R is a fully differential, low voltage 1.2 V/1.8 V/2.5 V 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 Microchip'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 200 mV (400 mV pp) 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 2.5 V ±5% core supply and a 1.2 V, 1.8 V or 2.5 V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY56011R is part of Microchip's high-speed, Precision Edge^® product line.
