SY58606U Product Brief 4.25Gbps Precision, 1:2 CML Fanout Buffer with Internal Termination and Fail Safe Input Description outputs are 400mV CML, with extremely fast rise/fall times The SY58606U is a 2.5/3.3V, high-speed, fully differential guaranteed to be less than 85ps. 1:2 CML fanout buffer optimized to provide two identical output copies with less than 15ps of skew and less than The SY58606U operates from a 2.5V ±5% supply or 3.3V 10pspp total jitter. The SY58606U can process clock ±10% supply and is guaranteed over the full industrial signals as fast as 3GHz or data patterns up to 4.25Gbps. temperature range (–40°C to +85°C). For applications that require LVPECL or LVDS outputs, consider Micrel’s The differential input includes Micrel’s unique, 3-pin input SY58607U and SY58608U, 1:2 fanout buffers with 800mV termination architecture that interfaces to LVPECL, LVDS and 325mV output swings respectively. The SY58606U is or CML differential signals, (AC- or DC-coupled) as small part of Micrel’s high-speed, Precision Edge® product line. as 100mV (200mVpp) without any level-shifting or termination resistor networks in the signal path.
