NOT RECOMMENDED FOR NEW DESIGNS  
SY89809L  
3.3V 1:9 High-Performance, Low-Voltage  
Bus Clock Driver  
General Description  
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, ultra-low 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.  
Precision Edge®  
Features  
3.3V core supply, 1.8V output supply for reduced power  
LVPECL and HSTL inputs  
9 differential HSTL (low-voltage swing) output pairs  
HSTL outputs drive 50-to-ground with no offset voltage  
500MHz maximum clock frequency  
Low part-to-part skew (200ps max.)  
Low pin-to-pin skew (50ps max.)  
Available in 32-pin TQFP  
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.  
Applications  
High-performance PCs  
Workstations  
Parallel processor-based systems  
Other high-performance computing
