Programmable Timing Control Hub™ for Next Gen P4™ processor
Recommended Application:
Chipset for P4 type processor with PCI-Express
Output Features:
• 2 - 0.7V current-mode differential CPU pairs
• 1 - 0.7V current-mode differential CPU/PCI-Express
selectable pair
• 6 - PCI, 33MHz
• 2 - REF, 14.318MHz
• 3 - 3V66, 66.66MHz
• 1 - 48MHz
• 1 - 24/48MHz
• 5 - PCI-Express 0.7V current mode differential pairs
Key Specifications:
• CPU outputs cycle-cycle jitter < 85ps
• 3V66 outputs cycle-cycle jitter < 250ps
• PCI outputs cycle-cycle jitter < 500ps
Features/Benefits:
• Programmable output frequency.
• Programmable asynchronous 3V66&PCI frequency.
• Programmable asynchronous PCI-Express frequency.
• Programmable output divider ratios.
• Programmable output skew.
• Programmable spread percentage for EMI control.
• Watchdog timer technology to reset system if system
malfunctions.
• Programmable watch dog safe frequency.
• Support I2C Index read/write and block read/write
operations.
• Uses external 14.318MHz reference input, external
crystal load caps are required for frequency tuning.
