General Description
The SY898533L is a 3.3V, low skew, 1:4 LVPECL fanout
buffer with two selectable clock input pairs. Most standard
differential input levels can be applied to the CLK, /CLK
pair while LVPECL, CML, or SSTL input levels can be
applied to the PCLK, /PCLK pair. 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 SY898533L operates from a 3.3V ±5% supply and is
guaranteed over the full industrial temperature range of
0°C to +70°C. The SY898533L is part of Micrel’s high-
speed, Precision Edge
product line.
