SY898533L Product Brief Precision Differential 3.3V Low Skew LVPECL 1:4 Fanout Buffer Description The SY898533L is a 3.3V, low skew, 1:4 LVPECL fanout The SY898533L operates from a 3.3V ±5% supply and is buffer with two selectable clock input pairs. Most standard guaranteed over the full industrial temperature range of differential input levels can be applied to the CLK, /CLK –0°C to +70°C. The SY898533L is part of Micrel’s high® pair while LVPECL, CML, or SSTL input levels can be speed, Precision Edge product line. applied to the PCLK, /PCLK pair. To eliminate runt pulses All datasheets and support documentation can be found on the outputs during asynchronous assertion/de-assertion on Micrel’s web site at: www.micrel.com. of the clock enable pin, the clock enable is synchronized with the input signal. ___________________________________________________________________________________________________________ Functional Block Diagram Precision Edge is a registered trademark of Micrel, Inc.
