Programmable Timing Control Hub™ For Mobile P4™ Systems

The 954309 is a CK410M clock synthesizer with additional SRC clock support. The 954309 provides a single-chip solution for mobile systems built with Intel P4-M processors and Intel mobile chipsets. The 954309 is driven with a 14.318MHz crystal and generates CPU outputs up to 400MHz.

Features

  • 2 - 0.7V current-mode differential CPU pairs
  • 9 - 0.7V current-mode differential SRC pair for SATA and PCI Express*
  • 1 - 0.7V current-mode differential CPU/SRC selectable pair
  • 4 - PCI (33MHz)
  • 1 - PCICLK_F, (33MHz) free-running
  • 1 - USB, 48MHz
  • 1 - DOT, 96MHz, 0.7V current differential pair
  • 1 - REF, double-strength 14.318MHz
  • CPU outputs cycle-cycle jitter < 85ps
  • SRC outputs cycle-cycle jitter < 125ps
  • PCI outputs cycle-cycle jitter < 500ps
  • +/- 100ppm frequency accuracy on USB
  • +/- 300 ppm accuracy clocks for Serial-ATA and PCI Express and CPU clocks
  • Supports spread spectrum modulation, 0 to -0.5% down spread for CPU, SRC and PCI clocks
  • Supports CPU clocks up to 400MHz
  • Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
  • Supports undriven differential CPU, SRC pair in PD# for power management.
