The SY58033U is a 2.5V/3.3V precision, high-speed, fully differential 400mV LVPECL 1:8 fanout buffer. The SY58033U is optimized to provide eight identical output copies with less than 20ps of skew and less than 10pspp total jitter. It can process clock signals as fast as 5.5GHz. The differential input includes Micrel's unique, 3-pin input termination architecture that allows the SY58033U to directly interface to LVPECL, CML, and LVDS differential signal (ACor DC-coupled) without any level-shifting or termination resistor networks in the signal path. The result is a clean, stub-free, low-jitter solution. The LVPECL (100k temperature compensated) outputs feature a 400mV typical swing into 50 loads, and provide an extremely fast rise/fall time guaranteed to be less than 80ps. The SY58033U operates from a 2.5V 5% supply or 3.3V 10% supply and is guaranteed over the full industrial temperature range (40C to +85C). Other high-speed 1:8 fanout buffers include the CML SY58031U and the 800mV LVPECL SY58032U. The SY58033U is part of Micrel's highspeed, Precision Edge product line.
