IDTCV152

DESCRIPTION:

FEATURES:

IDTCV152 is a 56 pin clock device, compliant with Intel CK410B

specification.The CPU output buffer is designed to support up to 400MHz

processor. This chiphas three PLLs inside forCPU,SRC/PCI, and48MHz

IOclocks. ThisdevicealsoimplementsBand-gapreferencedIREF toreduce

theimpactofVDD variationondifferentialoutputs,whichcanprovidemorerobust

systemperformance. EachCPUandSRC/PCIhasitsownSpreadSpectrum

selection,whichallows forisolatedchanges insteadofaffecting otherclock

groups.

• One high precision PLL for CPU, SSC, and N programming

• One high precision PLL for SRC/PCI, SSC, and N programming

• One high precision PLL for 48MHz

• Band-gap circuit for differential outputs

• Support spread spectrum modulation, down spread 0.5% and

others

• Support SMBus block read/write, index read/write

• Selectable output strength for REF, 48MHz, PCI

• Allows for CPU frequency to change to a higher frequency for

maximum system computing power

• Available in SSOP and TSSOP packages

OUTPUTS:

KEYSPECIFICATION:

• CPU CLK cycle to cycle jitter < 85ps

• SRC CLK cycle to cycle jitter < 100ps

• PCI CLK cycle to cycle jitter < 250ps

• 5*0.7V current –mode differential CPU CLK pair

• 4*0.7V current –mode differential SRC CLK pair

• 7*PCI, 3 free running, 33.3MHz

• 1*48MHz

• 2*REF
