  • 13 - SDRAM @ 3.3V, up to 200MHz.
  • 3 - 3V66 @ 3.3V, 2x PCI MHz.
  • 8 - PCI @3.3V.
  • 1 - 48MHz, @3.3V fixed.
  • 1 - 24/48MHz @ 3.3V.
  • 1 - REF @3.3V, 14.318MHz. Features:.
  • Support PC133 SDRAM.
  • Up to 200MHz frequency support.
  • Support power management through PD#.
  • Spread spectrum for EMI control (± 0.25% Center Spread or 0 to -0.5% down spread).
  • Uses external 14.31.
