PI6C3991  
3.3V High Speed Low-Voltage  
Programmable Skew Clock Buffer  
SuperClockTM  
Features  
Description  
• All output pair skew <100ps typical (250 Max.)  
• 3.75 MHz to 80 MHz output operation  
• User-selectable output functions  
— Selectable skew to 18ns  
ThePI6C3991offersselectablecontroloversystemclockfunctions.  
These multiple-output clock drivers provide the system integrator  
withfunctionsnecessarytooptimizethetimingofhigh-performance  
computer systems. Eight individual drivers, arranged as four pairs  
ofuser-controllableoutputs,caneachdriveterminatedtransmission  
lineswithimpedancesaslowas50Ohmwhiledeliveringminimaland  
specified output skews and full-swing logic levels (LVTTL).  
— Inverted and Non-Inverted  
— Operation at ½ and ¼ input frequency  
Each output can be hardwired to one of nine delay or function  
configurations.Delayincrementsof0.7nsto1.5nsaredeterminedby  
theoperatingfrequencywithoutputsabletoskewupto±6timeunits  
fromtheirnominal“zero”skewposition.Thecompletelyintegrated  
PLL allows external load and transmission line delay effects to be  
canceled. The user can create output-to-output delays of up to ±12  
time units.  
— Operation at 2X and 4X input frequency  
(input as low as 3.75 MHz)  
• Zero input-to-output delay  
• 50% duty-cycle outputs  
• LVTTL outputs drive 50 Ohm terminated lines  
• Operates from a single 3.3V supply  
• Low operating current  
Divide-by-twoanddivide-by-fouroutputfunctionsareprovidedfor  
additional flexibility in designing complex clock systems. When  
combinedwiththeinternalPLL,thesedividefunctionsallowdistri-  
butionofalow-frequencyclockthatcanbemultipliedbytwoorfour  
at the clock destination. This facility minimizes clock distribution  
difficulty while allowing maximum system user-clock speed and  
flexibility.  
• Availablein32-pinPLCC(J)package  
• Jitter < 200ps peak-to-peak (< 25ps RMS)
