SY56216RMG

SY56216R Low Voltage 1.2V/1.8V/2.5V CML Dual Channel Buffer 4.5GHz/6.4Gbps with Equalization General Description The SY56216R is a fully-differential, low-voltage 1.2V/1.8V/2.5V CML Dual Channel Buffer with input equalization. The SY56216R 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 200mV (400mVpp) 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 80ps. The SY56216R 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 SY56216R is part of Micrel’s highspeed, Precision Edge® product line. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
