SY898535L Fanout Buffer


SY898535L: precision differential 3.3 V, low skew, 1:4 LVCMOS/LVTTL-to-LVPECL fanout buffer


The SY898535L from Micrel is a 3.3 V, 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 3.3 V 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 3.3 V ±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.
