IDT5V991A  
3.3V PROGRAMMABLE  
SKEW PLL CLOCK DRIVER  
TURBOCLOCK™  
FEATURES:  
DESCRIPTION:  
• REF is 5V tolerant  
The IDT5V991Ais a highfanout3.3VPLLbasedclockdriverintended  
forhighperformancecomputinganddata-communicationsapplications.A  
keyfeatureoftheprogrammableskewistheabilityofoutputstoleadorlag  
the REF input signal. The IDT5V991A has eight programmable skew  
outputs infourbanks of2.Skewis controlledby3-levelinputsignals that  
may be hard-wired to appropriate HIGH-MID-LOW levels.  
• 4 pairs of programmable skew outputs  
Low skew: 200ps same pair, 250ps all outputs  
• Selectable positive or negative edge synchronization:  
Excellent for DSP applications  
• Synchronous output enable  
• Output frequency: 3.75MHz to 85MHz  
• 2x, 4x, 1/2, and 1/4 outputs  
Whenthe GND/sOE pinis heldlow,allthe outputs are synchronously  
enabled.However,ifGND/sOEisheldhigh,alltheoutputsexcept3Q0and  
3Q1 are synchronously disabled.  
• 3 skew grades:  
IDT5V991A-2: tSKEW0<250ps  
IDT5V991A-5: tSKEW0<500ps  
IDT5V991A-7: tSKEW0<750ps  
• 3-level inputs for skew and PLL range control  
• PLL bypass for DC testing  
Furthermore, when the VCCQ/PE is held high, all the outputs are  
synchronizedwiththe positive edge ofthe REFclockinput.WhenVCCQ/  
PEis heldlow,allthe outputs are synchronizedwiththe negative edge of  
REF. BothdeviceshaveLVTTLoutputswith12mAbalanceddriveoutputs.  
• External feedback, internal loop filter  
• 12mA balanced drive outputs  
Low Jitter: <200ps peak-to-peak  
Available in 32-pin PLCC Package
