Status: In Production
The SY58606U is a 2.5/3.3V, high-speed, fully differential 1:2 CML fanout buffer optimized to provide two identical output copies with less than 15ps of skew and less than 10pspp total jitter. The SY58606U can process clock signals as fast as 3GHz or data patterns up to 4.25Gbps.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) 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 400mV CML, with extremely fast rise/fall times guaranteed to be less than 85ps.The SY58606U 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 LVPECL or LVDS outputs, consider Micrel's SY58607U and SY58608U, 1:2 fanout buffers with 800mV and 325mV output swings respectively. The SY58606U is part of Micrel's highspeed, Precision Edge® product line.
