PI6C2408  
Zero-Delay Clock Buffer  
ProductFeatures  
Maximumratedfrequency:140MHz  
Lowcycle-to-cyclejitter  
Input to output delay, less than 150ps  
External feedback pin allows outputs to be synchronized  
to the clock input  
5V tolerant input*  
Operatesat3.3VVDD  
Test mode allows bypass of the PLL for system testing  
purposes (e.g., IBIS measurements)  
FunctionalDescription  
The PI6C2408 is a PLL-based, zero-delay buffer, with the ability  
to distribute eight outputs of up to 140 MHz at 3.3 V. Two banks of  
four outputs exist, and, depending on product option ordered, can  
supply either reference frequency, prescaled half frequency, or  
multiplied2xor4xinputclockfrequencies. ThePI6C2408familyhas  
a power-sparing feature: when input SEL2 is 0, the component will  
3-state one or both banks of outputs depending on the state of input  
SEL1. A PLL bypass test mode also exists. This product line is  
available in high-drive and industrial environment versions.  
An external feedback pin is used to synchronize the outputs to the  
input; the relationship between loading of this signal and the other  
outputs determines the input-output delay.  
The PI6C2408 is characterized for both commercial and industrial  
operation.  
Clock frequency multipliers ½x to 4x dependent on option

* FB_IN and CLKIN must reference the same voltage thresh-  
olds for the PLL to deliver zero delay skewing
