Device Overview

Summary

The SY898535L is a 3.3V, low skew, 1:4 LVCMOS/LVTTL-to-LVPECL fanout buffer with two selectable single ended clock inputs. The CLK0 and CLK1 accept LVCMOS or LVTTL input levels and translate them to 3.3V LVPECL levels. To eliminate runt pulses on the outputs during asynchronous assertion/de-assertion of the clock enable pin, the clock enable is synchronized with the input signal.The SY898535L operates from a 3.3V ±5% supply and is guaranteed over the full industrial temperature range of –40°C to +85°C. The SY898535L is part of Micrel’s high-speed, Precision Edge® product line.
