SY54011R

www.DataSheet.co.kr SY54011R Low Voltage 1.2V/1.8V CML 1:2 Fanout Buffer, 3.2Gbps, 3.2GHz General Description The SY54011R is a fully differential, low voltage 1.2V/1.8V CML 1:2 fanout buffer. It is optimized to provide two identical output copies with less than 15ps of skew and less than 10pspp total jitter. The SY54011R can process clock signals as fast as 3.2GHz or data patterns up to 3.2Gbps. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled from a 2.5V driver) as small as 100mV (200mVPP) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an integrated voltage reference (VREF-AC) is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 95ps. The SY54011R operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply and is guaranteed over the full industrial temperature range (–40°C to +85°C). The SY54011R is part of Micrel’s ® high-speed, Precision Edge product line. Datasheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
