Device Overview

Summary

The SY89645L is a 3.3V, fully differential, low skew, 1:4 LVDS fanout buffer that accepts LVTTL or LVCMOS inputs. It is capable of processing clock signals as fast as 650MHz. The LVDS signals are optimized to provide less than 40ps of output skew.The single-ended input takes a 3.3V LVTTL or LVCMOS, with a signal swing as small as 1.2V. The outputs are 280mV LVDS, with fast rise and fall times, guaranteed to be less than 400ps.The SY89645L operates from a 3.3V + 5% power supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY89645L is part of Micrel's Precision Edge® product line.
