IDTCV146  
PROGRAMMABLE FLEXPC™  
CLOCK FOR P4 PROCESSOR  
DESCRIPTION:  
FEATURES:  
IDTCV146is a 56pinclockdevice. The CPUoutputbufferis designedto  
supportupto400MHzprocessor. This chiphas three PLLs inside forCPU/  
SRC/PCI,SATA,and48MHz/DOT96IOclocks. OnededicatedPLLforSerial  
ATAclockprovides highaccuracyfrequency. This device alsoimplements  
Band-gapreferencedIREF toreducetheimpactofVDD variationondifferential  
outputs,whichcanprovidemorerobustsystemperformance.  
• One high precision PLL for CPU, with SSC and N program-  
mable  
• One high precision PLL for SRC/PCI/SATA, SSC and N pro-  
grammable  
• One high precision PLL for 96MHz/48MHz  
• Band-gap circuit for differential outputs  
• Supports spread spectrum modulation, down spread 0.5%  
• Supports SMBus block read/write, index read/write  
• Selectable output strength for REF  
EachCPU/SRC/PCI,SATAclockhasitsownSpreadSpectrumselection,  
whichallowsforisolatedchangesinsteadofaffecting otherclockgroups.  
Allows for CPU frequency to change to a higher frequency for  
maximum system computing power  
• Enhanced capacitance on XTAL_IN and XTAL_OUT pins  
Available in SSOP package  
OUTPUTS:  
• 2*0.7V current –mode differential CPU CLK pair  
• 6*0.7V current –mode differential SRC CLK pair, one  
SATA_SRC pair  
KEYSPECIFICATIONS:  
• CPU/SRC CLK cycle to cycle jitter < 85ps  
• SATA CLK cycle to cycle jitter < 85ps  
• PCI CLK cycle to cycle jitter < 250ps  
• One CPU_ITP/SRC selectable CLK pair  
• 6*PCI, two free running, 33.3MHz  
• 1*96MHz,1*48MHz  
• 2*REF
