SY56020R Datasheet | Micrel Semiconductor

.. Low Voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer 6.4Gbps with Equalization General Description The SY56020R is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with input equalization. The SY56020R 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 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 200m V (400m Vpp) 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 90ps. The SY56020R 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 SY56020R is part of Micrel’s highspeed, Precision Edge® product line. Datasheets and support documentation can be found on Micrel’s web site at: .micrel..
