The SY58032U is optimized to provide eight identical output copies with less than 20ps of skew and only 76fsRMS phase jitter. It can process clock signals as fast as 4GHz. The differential input includes Micrel’s unique, 3-pin input termination architecture that allows the SY58032U to directly interface to LVPECL, CML, and LVDS differential signals (AC- or DC-coupled) without any level-shifting or termination resistor networks in the signal path. The result is a clean, stub-free, low-jitter interface solution. The LVPECL (100k temperature compensated) outputs feature 800mV typical swing into 50ý loads, and provide an extremely fast rise/fall time guaranteed to be less than 110ps. The SY58032U 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 a higher high-speed 1:8 fanout buffer, consider the SY58031U or SY58033U. The SY58032U is part of Micrel’s high-speed, Precision Edge® product line.
