Overview
DATASHEET Programmable Timing Control HubTM for Mobile P4TM Systems 954226 Recommended Application: CK410M Compatible Main Clock Key Specifications: • CPU outputs cycle-cycle jitter < 85ps • PCI Express outputs cycle-cycle jitter < 125ps Output Features: • 2 - 0.
7V current-mode differential CPU pairs • 4 - 0.
7V current-mode differential PCI Express* pairs • 1 - 0.
7V current-mode differential CPU/PCI Express selectable pair • 1 - 0.
7V current-mode differential SATA pair • 1 - 0.
7V current-mode differential LCDCLK/PCI Express selectable pair • 4 - PCI (33MHz) • 2 - PCICLK_F, (33MHz) free-running • 1 - USB, 48MHz • 1 - DOT, 96MHz, 0.
7V current differential pair • 2 - REF, 14.
318MHz • SATA outputs cycle-cycle jitter < 125ps • PCI outputs cycle-cycle jitter < 500ps • +/- 300ppm frequency accuracy on CPU, PCI Express and SATA clocks • +/- 100ppm frequency accuracy on USB clocks Features/Benefits: • Supports tight ppm accuracy clocks for Serial-ATA and PCI Express • Supports programmable spread percentage and frequency • Uses external 14.
318MHz crystal, external crystal load caps are required for frequency tuning • Supports undriven differential CPU, PCI Express pair in PD for power management.
• PEREQ# pins to support PCI Express and SATA power management.
