ICS952601

Integrated Circuit Systems, Inc. ICS952601 Programmable Timing Control Hub™ for Next Gen P4™ processor Recommended Application: CK409 clock, Intel Yellow Cover part Output Features: 3 - 0.7V current-mode differential CPU pairs 1 - 0.7V current-mode differential SRC pair 7 - PCI (33MHz) 3 - PCICLK_F, (33MHz) free-running 1 - USB, 48MHz 1 - DOT, 48MHz 2 - REF, 14.318MHz 4 - 3V66, 66.66MHz 1 - VCH/3V66, selectable 48MHz or 66MHz Key Specifications: CPU/SRC outputs cycle-cycle jitter < 125ps 3V66 outputs cycle-cycle jitter < 250ps PCI outputs cycle-cycle jitter < 250ps CPU outputs skew: < 100ps +/- 300ppm frequency accuracy on CPU & SRC clocks Features/Benefits: Supports tight ppm accuracy clocks for Serial-ATA. Supports spread spectrum modulation, 0 to -0.5% down spread. Supports CPU clks up to 400MHz in test mode. Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning. Supports undriven differential CPU, SRC pair in PD# and CPU_STOP# for power management.
