SY89809AL Product Brief 3.3V 1:9 High-Performance, Low-Voltage Bus Clock Driver Description The SY89809AL is a high-performance bus clock driver This avoids any chance of generating a runt clock pulse with nine differential High-Speed Transceiver Logic (HSTL) when the device is enabled/disabled as can happen with output pairs. The part is designed for use in low-voltage an asynchronous control. (3.3V/1.8V) applications, which require a large number of The SY89809AL features low pin-to-pin skew (15ps outputs to drive precisely aligned, ultra-low skew signals to maximum) and low part-to-part skew (200ps maximum). their destination. The input is multiplexed from either HSTL The SY89809AL is available in a single space-saving or Low-Voltage Positive-Emitter-Coupled Logic (LVPECL) package, enabling a lower overall cost solution. by the CLK_SEL pin. The Output Enable (OE) is Datasheets and support documentation can be found on synchronous so that the outputs will only be Micrel’s web site at: www.micrel.com. enabled/disabled when they are already in the LOW state. ____________________________________________________________________________________________________________ Block Diagram Precision Edge is a registered trademark of Micrel, Inc Micrel, Inc.
