简介

9LPRS501 follows Intel CK505 Yellow Cover specification. This clock synthesizer provides a single chip solution for next generation Intel processors and Intel chipsets. 9LPRS501 is driven with a 14.318MHz crystal. It also provides a tight ppm accuracy output for Serial ATA and PCI-Express support.

特性

  • 2 - CPU differential low power push-pull pairs
  • 10 - SRC differential low power push-pull pairs
  • 1 - CPU/SRC selectable differential low power push-pull pair
  • 1 - SRC/DOT selectable differential low power push-pull
  • 5 - PCI, 33MHz
  • 1 - PCI_F, 33MHz free running
  • 1 - USB, 48MHz
  • 1 - REF, 14.318MHz
  • CPU outputs cycle-cycle jitter < 85ps
  • SRC output cycle-cycle jitter < 125ps
  • PCI outputs cycle-cycle jitter < 250ps
  • +/- 100ppm frequency accuracy on CPU & SRC clocks
  • Does not require external pass transistor for voltage regulator
  • Integrated series resistors on differential outputs, Zo=50Ω
  • Supports spread spectrum modulation, default is 0.5% down spread
  • Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
  • One differential push-pull pair selectable between SRC and two single-ended outputs
