DESCRIPTION  
HSTL outputs drive 50to ground with no  
The SY89809L is a High-Performance Bus Clock Driver  
with 9 differential HSTL (High-Speed Transceiver Logic)  
output pairs. The part is designed for use in low-voltage  
(3.3V/1.8V) applications which require a large number of  
outputs to drive precisely aligned, ultralow skew signals to  
their destination. The input is multiplexed from either HSTL  
or LVPECL (Low-Voltage Positive-Emitter-Coupled Logic)  
by the CLK_SEL pin. The Output Enable (OE) is  
synchronous so that the outputs will only be enabled/  
disabled when they are already in the LOW state. This  
avoids any chance of generating a runt clock pulse when  
the device is enabled/disabled as can happen with an  
asynchronous control.

LOGIC SYMBOL  
CLK_SEL  
The SY89809L features low pin-to-pin skew (50ps max.)  
and low part-to-part skew (200ps max.)—performance  
previously unachievable in a standard product having such  
a high number of outputs. The SY89809L is available in a  
single space saving package, enabling a lower overall cost  
solution.
