Optimized to provide two identical output copies with less than 15ps of skew and less than 10ps(pk-pk) total jitter, the SY58013U can process clock signals as fast as 6GHz or data patterns up to 10.7Gbps. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS, and CML differential signals, (AC- or DC-coupled) as small as 100mV without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an on-board output reference voltage (VREF- AC) is provided to bias the VT pin. The outputs are 400mV LVPECL compatible, with extremely fast rise/fall times guaranteed to be less than 80ps. The SY58013U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (–40 °C to +85°C). For applications that require greater output swing or CML compatible outputs, consider the SY58012U 1:2 fanout buffer with 800mV LVPECL outputs, or the SY58011U 1:2 fanout buffer with 400mV CML outputs. The SY58013U is part of Micrel’s high-speed, Precision Edge® product line. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
