NB2308A  
3.3 V Zero Delay  
Clock Buffer  
The NB2308A is a versatile, 3.3 V zero delay buffer designed to  
distribute high--speed clocks. It is available in a 16 pin package. The  
part has an on--chip PLL which locks to an input clock presented on  
the REF pin. The PLL feedback is required to be driven to FBK pin,  
and can be obtained from one of the outputs. The input--to--output  
propagation delay is guaranteed to be less than 250 ps, and the  
output--to--output skew is guaranteed to be less than 200 ps.  
The NB2308A has two banks of four outputs each, which can be  
controlled by the select inputs as shown in the Select Input Decoding  
Table. If all the output clocks are not required, Bank B can be  
three--stated. The select input also allows the input clock to be directly  
applied to the outputs for chip and system testing purposes.  
Multiple NB2308A devices can accept the same input clock and  
distribute it. In this case the skew between the outputs of the two  
devices is guaranteed to be less than 700 ps.

The NB2308A is available in five different configurations (Refer to  
NB2308A Configurations Table). The NB2308AI1 is the base part,  
where the output frequencies equal the reference if there is no counter  
in the feedback path. The NB2308AI1H is the high--drive version of  
the --1 and the rise and fall times on this device are much faster.  
The NB2308AI2 allows the user to obtain 2X and 1X frequencies on  
each output bank. The exact configuration and output frequencies  
depends on which output drives the feedback pin. The NB2308AI3  
allows the user to obtain 4X and 2X frequencies on the outputs.  
The NB2308AI4 enables the user to obtain 2X clocks on all outputs.  
Thus, the part is extremely versatile, and can be used in a variety of  
applications.

NB2308A  
Zero Delay and Skew Control  
All outputs should be uniformly loaded to achieve Zero  
Delay between input and output.  
To close the feedback loop of the NB2308A, the FBK pin  
can be driven from any of the eight available output pins.  
The output driving the FBK pin will be driving a total load  
of 7 pF plus any additional load that it drives. The relative  
loadingofthisoutput(withrespecttotheremainingoutputs)  
can adjust the input--output delay. This is shown in Figure 3.  
For applications requiring zero input--output delay, all  
outputs including the one providing feedback should be  
equally loaded. If input--output delay adjustments are  
required, use the above graph to calculate loading  
differences between the feedback output and remaining  
outputs. For zero output--output skew, be sure to load  
outputs equally.
